Description

Technical Field

[0001] The utility model belongs to the technical field of accessories for portable devices connected with cables and to be connected to wearable components, and particularly relates to a backpack for a portable device connected with cables and to be connected to a wearable component. Background Art

[0002] Recently, portable devices such as electroencephalogram and near-infrared brain functional imaging technology have been developed, enabling users to carry them conveniently during exercise and collect relevant physiological data. Generally, during exercise, these portable devices are connected with cables for transmitting electrical signals or optical signals and are to be connected to wearable components such as head caps and cuffs.

[0003] Taking functional near-infrared spectroscopy (fNIRS) as an example, this is a newly emerging non-invasive brain functional imaging technology in recent years. fNIRS mainly utilizes the difference characteristics of the absorption rates of oxygenated hemoglobin and deoxygenated hemoglobin in brain tissue for near-infrared light of different wavelengths to directly and real-time detect the hemodynamic activities of the cerebral cortex. By observing such hemodynamic changes, the neural activities of the brain can be inferred through the neurovascular coupling law. In recent years, fNIRS has been gradually applied to the research in the field of cognitive neuroscience. This technology can safely, non-invasively and at low cost monitor the functional activities of different regions of the cerebral cortex, providing useful references for the evaluation of cognitive dysfunction and the study of the pathogenesis of neuropsychiatric diseases.

[0004] In order to facilitate users to perform near-infrared brain functional imaging while walking, a portable device is used in cooperation with a head cap. The head cap is provided with near-infrared emission and reception probes, and when worn on the head, it collects the blood oxygen information of the cerebral cortex. The portable device is connected to the near-infrared probes through multiple cables. The cables contain optical fibers to transmit near-infrared light to the emission probes and receive near-infrared light from the reception probes, so that it is convenient for users to collect near-infrared brain function data outdoors. However, since the portable device and the head cap are connected through multiple cables, it is inconvenient to put the portable device into a common storage bag, and there is no convenient and reasonable arrangement and storage for the multiple cables. If the optical fibers are folded and bent improperly, they are easily broken, affecting the collection process and reducing the user experience. Summary of the Utility Model

[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted in this utility model.

[0033] As Figure 1 and Figure 2 shown, an embodiment of this utility model provides a backpack for a portable device. The portable device is connected with a plurality of cables 10 and is connected to a wearable member via the cables 10. The backpack includes double shoulder straps 1, a bag body 2, and a flap 3 that can be opened and closed relative to the bag body 2. The bag body 2 includes a front piece 4, side pieces 5, and a back 6. At positions close to the inner sides of the longitudinal edges on both sides of the front piece 4, a first zipper 7 and a second zipper 8 are respectively provided. Both the first zipper 7 and the second zipper 8 extend downward from the upper edge of the front piece 4 by more than half of its height. The flap 3 is provided with a first opening 9 for threading the plurality of cables 10. The periphery of the first opening 9 of the flap 3 is slit (cut) to form a first small piece 11 and a second small piece 12. The first small piece 11 and the second small piece 12 can be opened and joined to each other, and when opened, form an open passage for receiving the cables 10 into the first opening 9.

[0034] After the first zipper 7 and the second zipper 8 of the front piece 4 are unzipped, a part of the front piece 4 can be rolled up or lifted relative to the front piece 4, so that a larger space can be left for loading the portable device into the bag body 2, enabling the portable device to be more easily and smoothly loaded into the bag body 2 without having to provide a larger loading opening on the bag body 2 to load the portable device. Only a loading opening of a suitable size is required. After the zippers are zipped up, the adapted inner cavity can reduce the shaking of the stored portable device and be more adapted to the shape of the portable device. The loading opening is the opening of the bag body formed by the front piece, the side pieces, and the back.

[0035] Since the front piece 4 and the side piece 5 are generally connected by means such as thermal pressing, etc., the connection position between the front piece 4 and the side piece 5 is relatively difficult to be rolled up. Therefore, the first zipper 7 and the second zipper 8 are arranged at positions closer to the inner side of the longitudinal edges on both sides of the front piece 4 instead of on the side piece 5, which is conducive to the operation of the user and the smooth loading of the portable device.

[0036] The wearable member is for wearing on the user's head. Since the wearable member is provided with a plurality of detection points, there are multiple cables 10 connected between the portable device and the wearable member. There may be more than a dozen to dozens of cables 10. Therefore, the multiple cables 10 are prone to entanglement and disorder.

[0037] The flip cover 3 is provided with a first opening 9 for the multiple cables 10 to pass through. By opening the first small piece 11 and the second small piece 12, the multiple cables 10 can be conveniently sorted directly to the first opening 9. If there is no slit provided, one end of the multiple cables 10 needs to drill through the first opening 9 to sort the multiple cables 10 to the first opening 9, which is inconvenient to operate. Moreover, the ends of the multiple cables 10 are connected with detection members. In the case of a large number of cables 10, it is not convenient to drill through the first opening 9. By providing the slit, opening the first small piece 11 and the second small piece 12 forms an open passage, and the multiple cables 10 can be sorted smoothly, avoiding breakage caused by improper folding and bending of the optical fibers. When fixing the first small piece 11 and the second small piece 12, it can prevent the multiple cables 10 from slipping out of the first opening 9. Moreover, this sorting method can make the first opening 9 that binds the multiple cables 10 have a size adapted to the circumference of the multiple cables 10, without relying on a larger opening to facilitate the multiple cables 10 to drill through the opening, and can also form a more suitable constraint on the multiple cables 10, reducing the shaking after sorting. Therefore, it can greatly facilitate the user's operation of loading the backpack and can also improve the user's experience.

[0038] The process of loading the portable device is as follows: Open the flip cover 3, unzip the first zipper 7 and the second zipper 8 of the front piece 4, and then load the portable device into the bag body 2; Open the first small piece 11 and the second small piece 12, and put the cables 10 into the open passage of the first opening 9. Simple operations can load the portable device, and can also reduce the entanglement of the multiple cables 10 and the shaking of the portable device and the multiple cables during use.

[0039] As Figure 2 shown, in some embodiments, the first small piece 11 and the second small piece 12 are joined to each other via Velcro together with snap buttons. The cooperation of Velcro and snap buttons can not only be convenient to open, but also improve the constraint on the multiple cables 10, so that the multiple cables 10 are bound within the first opening 9.

[0040] In some embodiments, the wearable component includes a headcap equipped with near-infrared probes, and the portable device includes a near-infrared brain function imaging device. After the headcap with near-infrared probes collects near-infrared data, it is transmitted to the near-infrared brain function imaging device. The near-infrared brain function imaging device is placed in the bag body 2 of the backpack, and the headcap with near-infrared probes is worn on the user's head.

[0041] As Figure 1 shown, in some embodiments, on the outer side of the upper back section of each strap of the double shoulder strap 1, there are paired cable restraint straps 13, and the paired cable restraint straps 13 can be opened and fastened to each other via snap buttons. Although multiple cables 10 are constrained in the first opening 9, since each cable 10 is relatively long and the number of cables 10 is also large, when the user uses it outdoors, the multiple cables 10 are prone to entanglement and chaos. As Figure 4 and Figure 5 shown, through the two cable restraint straps 13, the multiple cables 10 can be constrained in an S shape, reducing the chaos and entanglement of the multiple cables 10; the multiple cables 10 can also be divided into two halves and constrained by different cable restraint straps 13, reducing the chaos and entanglement of the multiple cables 10 and enhancing the user experience.

[0042] In some embodiments, the paired cable restraint straps 13 are elastic and are equipped with at least two levels of snap buttons, and different accommodation spaces are formed when each level of snap button is fastened. The elastic cable restraint straps 13 can restrain the cables 10 and will not cause much pressure on the cables 10. The two-level snap buttons can be used to restrain different numbers of cables 10 to form a suitable binding force on the multiple cables 10.

[0043] As Figure 7 shown, in some embodiments, the backpack further includes a chest strap 14, and the chest strap 14 is connected to the double shoulder strap 1. When the user uses the backpack, the backpack can be further fixed through the chest strap 14 to improve the stability of the backpack. In addition, the backpack can also include a waist strap to improve the stability of the backpack.

[0044] As Figure 1 、 Figure 2 and Figure 6 shown, in some embodiments, the front panel 4 is provided with a front pocket 15 for accommodating a battery. A third opening 16 is formed on the first side of the front pocket 15 to allow the wire to pass through, and a fourth opening 17 is also formed on the side panel 5 on the first side to insert the passing wire and connect it to the power supply interface of the portable device. The near-infrared brain function imaging device needs a battery for power supply. The battery and the near-infrared brain function imaging device are placed separately to avoid mutual influence. Through the third opening 16 of the front pocket 15 and the fourth opening 17 of the side panel 5, it is convenient to connect the wire to the battery and the near-infrared brain function imaging device.

[0045] As Figure 2As shown, in some embodiments, a first wire binding strap 18 and a second wire binding strap 19 are respectively disposed above and below the fourth opening 17. The first wire binding strap 18 and the second wire binding strap 19 each form a binding space via snap buttons. The excess length of the wire is constrained by the first wire binding strap 18 and the second wire binding strap 19. This prevents the excess wire from scraping against other objects and detaching from the battery and the near-infrared brain function imaging device when the user is moving around.

[0046] As Figure 3 shown, in some embodiments, at the position corresponding to the tops of the first zipper 7 and the second zipper 8, an elastic ring 20 is fixedly provided on the side piece 5 for fixing the pull head 24 pulled to the top. When the pull head 24 is pulled to the top of the zipper, it passes through the elastic ring 20. The elastic ring 20 can fix the pull head 24 by winding around the pull head 24 or tying it to the pull head 24.

[0047] After the pull head 24 is fixed, during use by the user, it is possible to prevent the pull head 24 from being displaced significantly due to the overall shaking of the backpack or sliding down due to gravity, and to avoid a large gap between the front piece 4 and the flip cover 3, which may cause the near-infrared brain function imaging device to fall out of the bag body 2.

[0048] As Figure 3 shown, in some embodiments, a pair of tightening snap buttons 23 are provided on the upper part of the side piece 5 so as to tighten the bag body 2 via snapping. When snapping, the side piece 5 is folded and tightened, reducing the excess space in the bag body 2, reducing the shaking of the near-infrared brain function imaging device in the bag body 2, and avoiding the problems of unstable signals and poor user experience when the user carries the backpack.

[0049] As Figure 1 shown, in some embodiments, after the portable device is loaded into the bag body 2, a fifth opening 21 is formed at the position corresponding to its power switch. A raised portion is formed at the periphery of the fifth opening 21. The fifth opening 21 facilitates the user to operate the power switch of the portable device. The raised portion at the periphery can protect the power switch from accidental pressing operations.

[0050] As Figure 1 shown, in some embodiments, after the portable device is loaded into the front piece 4, a sixth opening 22 is provided at the position corresponding to the indicating portion of the portable device so that the indicating portion is visible. The indicating portion may include any one of an indicator light and a display screen, which will not be elaborated here. Through the sixth opening 22, the user can directly view the status of the portable device without having to take the portable device out of the backpack to view the relevant indicating portion information.

[0051] In some embodiments, ventilation mesh holes are provided at the position of the side piece 5 corresponding to the heat dissipation openings of the portable device to facilitate heat dissipation of the portable device.

[0052] The above description is intended to be illustrative and not restrictive, and those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more aspects thereof) can be used in combination with each other, and considering these embodiments, they can be combined with each other in various combinations or permutations.
