Description

A kind of function expansion component

Technical field

This application involves a kind of function expansion component for realizing one or more functions is connect with host.

Background technology

Currently, being the interface that fixed quantity is arranged on existing portable equipment or intelligent terminal, an interface is only It can be attached with an equipment.For example, being set on Portable sleep monitor, there are one interfaces, are the companies for electrocardioelectrode It connects, if the blood oxygen detection function of sleep monitor need to be increased or be continuously increased new function module interface on host, this Sample can cause host constantly to update.If in the case where not changing host interface, need to remake blood oxygen electrocardio compound electric Polar curve is used for the acquisition of electrocardiosignal and blood oxygen signal；If the function of temperature monitoring need to be further added by, then being connect not changing host In the case of mouthful, blood oxygen electrocardio body temperature compound electric polar curve need to be remake.Though above method solves the problems, such as but cable repeats profit It is low with rate, cause huge waste；Meanwhile poor user experience, use is cumbersome, and difference need to be repeatedly matched according to different test purposes The cable of type.

Utility model content

The purpose of this utility model is with providing a kind of function expansion component, never changing host interface for solution the case where The problem of lower increase function, and it is easy to operate, combination is flexible.

The technical scheme that the utility model is provided is as follows：

A kind of function expansion component, including link block and functional unit, link block are equipped with and are used for and device Host One male mouth of communication connection and the female mouth being electrically connected with male mouth, functional unit parallel connection access the connection circuit of male mouth and female mouth.

Further, male mouth is all made of digital total with the electric connection mode of female mouth and the electric connection mode of functional unit access The connection type of line, such as IIC.

Further, the functional unit is human body physiologic signal monitoring channel, such as electrocardiogram acquisition channel, blood oxygen saturation It spends acquisition channel, body temperature acquisition channel, sound of snoring acquisition channel, body and moves acquisition channel, nasal airflow acquisition channel etc..

Further, male mouth and female mouth are same type of interface, and the function expansion component can multilayer cascade use.

Preferably, male mouth and female mouth are USB interface.

Further, male mouth, female mouth and functional unit are set to the different location of link block, and three is in function expansion component Multilayer will not mutually limit use when cascading because of position relationship.

Preferably, link block main body substantially cuboid, male mouth are respectively arranged on the two sides of link block opposition with female mouth On, functional unit is set in the arbitrary one side at remaining four sides.

It, can be new as needed in the case where not changing host interface using function expansion component provided by the utility model Increase test function, a variety of test functions can be increased by being applied in combination, easy to operate, and combination is flexible.

Specific implementation mode

It elaborates below in conjunction with the accompanying drawings to a kind of function expansion component of the utility model, electric connection mode is all made of Iic bus is attached.

Embodiment one

Fig. 1 shows a kind of structural schematic diagram of function expansion component of the utility model.As shown in Figure 1, the Function Extension Component includes functional unit 200 and link block 100, and link block 100 is equipped with 110 and one female mouth 120 of a public mouth, wherein Public mouth 110 with main-machine communication for connecting, and interface type is adapted with host, and female mouth can be used for and other function expansion components Connection.Male mouth 110 is electrically connected with female mouth 120 in the form of iic bus, and functional unit 200 accesses public mouth with iic bus parallel connection 110 in the connection circuit of female mouth 120.Functional unit is human body physiologic signal monitoring unit, such as electrocardiogram acquisition unit, blood oxygen Collecting unit, body temperature collecting unit, sound of snoring collecting unit, body move collecting unit, nasal airflow collecting unit etc..When public mouth 110 with When host interface communicates to connect, the data that functional unit 200 acquires can be directly transferred to host by public mouth 110.

Embodiment two

Fig. 2 and Fig. 3 show the embodiments for when functional unit being specially electrocardiogram acquisition unit, as shown in Figures 2 and 3, should Function expansion component is specially electrocardiogram acquisition function expansion component, including electrocardiogram acquisition unit 201 and link block 101, connection The substantially cuboid of module 101, electrocardiogram acquisition unit 201 are stretched out from one side, electrocardiogram acquisition unit 201 and link block It is fixedly connected between 101 non-dismountable.It is additionally provided with the public mouth 111 of a usb type in link block 101, opposes with public mouth 111 One side be equipped with female mouth 121 of a usb type, wherein public mouth 111 with main-machine communication for connecting.Male mouth 111 and female mouth 121 electrical connections, the male mouth 111 in parallel that accesses of electrocardiogram acquisition unit 201 are connect with female mouth 121 in circuit.When the functional component module Be connected with host operation when, female mouth 121 is not connected with other modules, and electrocardiogram acquisition unit 201 is by the transmission of the electrocardiosignal of acquisition To public mouth 111, electrocardiosignal is sent to host by public mouth 111 again.

Embodiment three

Fig. 4 shows another embodiment of the utility model, and two kinds of different function extension elements are applied in combination, work( Can unit be respectively electrocardiogram acquisition unit 201 and blood oxygen collecting unit 202, concrete structure with it is consistent in embodiment two.Connection Module 102 is connected by the male mouth 112 in link block 102 with female mouth 121 in link block 101 with 101 It connects, host port 300 can be led to the electrocardiosignal of acquisition with 101 module of rotation visit and 102 modules, electrocardiogram acquisition unit 201 It crosses public mouth 111 and is transmitted to host port 300, meanwhile, public mouth 111 receives the blood oxygen letter acquired from blood oxygen collecting unit 202 Number, it is equal to electrocardiogram acquisition unit 201 and blood specimen collection unit 202 while carry is on host port 300.That is host port The 300 existing electrocardiosignal of signal has blood oxygen signal again.

A kind of function expansion component of the utility model has been made specifically above in conjunction with the drawings and specific embodiments It is bright, but do not invent and be not limited to the above, for example, can the same function expansion component of multiple functional units be used together, this Sample can carry out the test of same feature for multiple objects and only need a device Host.
