detailed description

The invention will now be further described with reference to the drawings and embodiments.

The invention mainly relates to a special holding device suitable for use in a mobile phone or other such as a tablet computer or an mp3 player. The holding device not only improves the holding reliability of using these electronic products, but also prevents falling; more importantly, By using the holding device, the operation capability of the user's single hand grip can be significantly improved, and by using the device, the user can realize the one-hand manipulation of the large screen touch screen electronic product. As shown in FIG. 1 and FIG. 2, in the present invention, a holding device for a mobile phone is composed of a holding belt 13 and a fixing base 12, and the two ends of the holding belt 13 are connected to the fixing base 12, The holder 12 is used for fixing to the mobile phone. The fixing base 12 is mainly for realizing the connection between the holding device and the mobile phone or other electronic device, for example, the holding device can be fixed on the mobile phone or other electronic products by bonding or snapping. However, since the surface of the existing electronic products is relatively smooth and flat, it is preferable to use a bonding fixing method to fix the holding device on the above-mentioned electronic product. Another suitable mode of the present invention is that in the production process of the electronic product, the mobile phone is directly integrated into the mobile phone, and the fixed seat 12 is connected with the body of the mobile phone. For the holding device, it mainly includes two states: one is that the storage state should be hidden as much as possible, that is, it does not affect the appearance of the mobile phone; the second is that when used, it needs to be extended to form a holding ring. At the same time, it has a certain degree of firmness and comfort.

As shown in FIG. 1 to FIG. 6 , the present invention relates to a mobile phone holding device, which is composed of a holding belt 13 and a fixing base 12 , and both ends of the holding belt 13 are connected with the fixing base 12 . The connection mentioned here has two meanings, as shown in FIG. 5 and FIG. 6, one of which refers to the direct fixing between the end of the holding strap 13 and the fixing seat 12, and the fixing manner may be a snapping manner, or A through hole is provided at one end of the grip belt 13 and fixed by a pin shaft. There are many similar fixing methods, which are not described here. The second method is to slide at least one end of the holding belt 13 which will be mentioned below. The fixing manner of the insertion into the telescopic cavity 14 is a movable fixing manner. The fixing manner is mainly used to realize the extension length adjustment of the holding strap 13 so that the above-mentioned holding strap 13 can be adjusted by telescopic adjustment. Adapt to the user's finger thickness is different. The fixing seat 12 serves as the main body of the whole mechanism, and when the holding device of the independent structure is used, it is a plastic piece with a sticker at the bottom; and when the holding device is integrated with the mobile phone or other human screen electronic devices, Then, the fixing base 12 is combined with the above-mentioned electronic device body as a whole. As shown in FIG. 5 and FIG. 6 , at least one end of the fixing base 12 is provided with a telescopic cavity 14 as a space for storing and accommodating the holding tape 13 , and the holding tape 13 is inserted into the telescopic cavity 14 and In the sliding direction, a length adjusting device is disposed between the telescopic cavity 14 and the grip belt 13, and the grip belt 13 is locked by the above-described length adjusting device. As shown in Figures 3 and 4, this structure is in the grip belt 13 The telescopic chamber 14 is disposed at both ends, and both ends of the grip belt 13 can be extended and contracted, so that the adjustment length of the grip belt 13 can be increased. The length adjusting device in the present invention is formed by the ratchet teeth 15 and the pawls 17 on the grip belt, and the grip belt 13 is inserted into the grip belt when the grip belt 13 is pulled out to an appropriate length. In the finger ring formed by the 13, the grip belt 13 generates an upwardly lifting force, so that the ratchet teeth 15 and the pawls 17 on the grip belt 13 are engaged with each other, thereby realizing the fixing of the length of the grip belt. The inside of the cavity or the opening attachment of the telescopic cavity 14 is provided with a pawl 17, and the distance between the pawl 17 and the bottom surface of the cavity is slightly larger than the thickness of the holding tape 13 to ensure that the holding tape 13 can be telescopically moved. The holding device is used when the mobile phone or the large-screen electronic product is used, and the holding tape 13 is taken out from the telescopic cavity 14 when the holding tape 13 is extended to a length suitable for the user's finger. The above-mentioned holding belt 13 is locked by the length adjusting device. At this time, the holding belt 13 forms a finger ring for inserting a finger. Since the holding device is fixed integrally with the mobile phone, the finger is inserted into the above. With the grip belt 13, it is possible to reliably hold the mobile phone with one finger. Compared with the current use of the palm-handling mobile phone, the above-mentioned mobile phone holding device can increase the length of half a palm to operate the mobile phone screen. Even with a five- or even six-inch display, you can still use your thumb to touch anywhere on the screen with one hand. After use, the above-mentioned grip belt can be taken back into the telescopic cavity 14.

As shown in FIG. 9-12, in order to make the above-mentioned holding device more beautiful and provide a storage space for the holding belt 13, a receiving cavity 11 is disposed on the fixing base 12, and the receiving cavity is provided. 11 is an upper open cavity having a shape matching with the grip belt 13. The length of the opening of the accommodating cavity 11 is generally similar to the diameter of a human finger. With this length, after the grip belt 13 is extended, the formed ring and the human finger have For better fit, the length of the opening of the accommodating cavity 11 is too long, and it is easy to fall off after being inserted into the finger; and the length of the opening of the accommodating cavity 11 is too short, so that the degree of control of the mobile phone is reduced, and the mobile phone is more likely to swing left and right. . The holding belt 13 is placed in the accommodating cavity 11, and the telescopic cavity 14 is located on the side of the accommodating cavity 11. As shown in FIG. 11 and FIG. 12, in the present invention, the telescopic cavity 14 is provided in two ways, one is disposed at one end of the accommodating cavity 14, and the structure is actually one end of the holding strap 13 and fixed. The seat 12 is fixed, and for the structure after the accommodating cavity 11 is provided, one end of the holding belt 13 can be fixed at one end of the accommodating cavity 11, and the other end is inserted into the accommodating cavity 11 and another one. In the side telescopic cavity 14, in practice, such an arrangement allows one end of the grip belt 13 to be telescopic; as shown in FIG. 9 and FIG. 10, and another telescopic cavity 14 is provided at both ends of the accommodating cavity 11. In terms of structure, both ends of the grip belt 13 need to be inserted into the corresponding telescopic cavity 14, that is, both ends of the grip belt 13 can be expanded and contracted.

Considering that the shape of the current mobile phone or other electronic devices is very beautiful, in order to avoid the influence of setting the holding device on the shape of the mobile phone or other electronic devices. The present invention also provides a accommodating chamber cover plate. As shown in FIG. 9 and FIG. 10, the holding belt 13 is provided with a accommodating chamber cover plate 16, and the accommodating chamber cover plate 16 and the accommodating chamber. 11 opening shapes match The accommodating chamber cover 16 and the holding belt 13 are integrally formed, that is, extended on the holding belt 13. By using the accommodating chamber cover 16, there are two advantages, as shown in Fig. 10, one of which is to close the opening of the accommodating chamber 11 when the holding device is not used. When used, it is preferable to set the holding tape 13 to the same color as the casing of the mobile phone, so that when the cover of the chamber cover 16 is accommodated, there is almost no influence on the shape of the mobile phone. In addition, the accommodating cavity cover 16 is preferably slightly wider than the holding strap 13 so that the holding device formed by the accommodating cavity cover 16 is wider and thicker, and the utility model can obviously improve the comfort during use. Simultaneously improve the ability to control.

The present invention also provides an accommodating chamber cover of another structure, as shown in FIG. 11 and FIG. 12, that is, the holding belt 13 is provided with a accommodating chamber cover 16, and the accommodating chamber cover The plate 16 is matched with the opening shape of the accommodating cavity 11 , and the accommodating cavity cover 16 is a jacket that is sleeved on the holding belt 16 , and the through hole section of the accommodating cavity cover 16 is matched with the holding belt 13 . And can slide on the grip belt 13. The accommodating chamber cover 16 of such a structure has the advantage that it can be slid on the holding belt 13, and the force of the accommodating chamber cover 16 is appropriately moved when it is used, so that it is placed on the finger. Larger position can significantly reduce finger force and improve comfort. In addition, the accommodating chamber cover 16 of such a structure is particularly suitable for use in a holding device in which the telescopic chamber 14 is provided at one end. The above-mentioned accommodating cavity cover 16 is preferably made of a soft material such as rubber or silicone to improve the comfort of use, and the holding reliability can be improved by increasing the friction.

The grip belt 13 is one of the key components in the present invention. And under the same principle, the grip belt 13 can be derived from a variety of structures. The surface of the holding belt 13 is provided with regular protrusions or pits or holes to form a holding belt limiting structure. In fact, the principle of the surface structure of the holding belt 13 is the same as long as the surface of the holding belt 13 has a certain surface. The specific structure, so that the length adjusting device mentioned below can be matched with it, thereby realizing the locking of the holding belt 13 at any position. The above mentioned bumps, pits and holes are the holding belts 13 for realizing The structure required for the snap lock between the length adjustment device. First, the protrusion is a zigzag structure disposed on both sides of the ratchet or the grip belt on the grip belt, and the mating relationship mentioned here includes the following: First, the grip belt is provided with a rack As shown in FIG. 3-6 and FIG. 9-12, the tooth shape of the tooth is the same as that of the ratchet, and the length adjusting device disposed in the telescopic cavity 14 naturally adopts the spine described above. The teeth 15 are matched with the shape of the pawl 17 so that the locking between the two can be achieved at any position. Secondly, as shown in FIG. 37, at least one end of the holding belt 13 is provided with a zigzag shape. The structure, the zigzag shape needs to be aligned at both ends, and the serration is an "I" shaped opening, and the length adjusting device in the corresponding telescopic cavity 14 is a limiting piece 26 of a "concave" structure symmetrically fixed. When the grip belt 13 is lifted upward, the length adjustment device control can be removed, the grip belt 13 can be extended by the extension of the telescopic chamber 14, and the grip belt can be pressed down to re-lock. Figure 37 herein shows a 180 degree flip in order to show its structure; third, as shown in Figures 35 and 36, the grip belt 13 can also cut the U-shaped slit equidistantly from the grip belt 13, and then U-shaped incision in the middle of the tongue 25, the same type of ratchet structure can be formed, the corresponding length adjusting device can be a pawl structure, or can be a square hole structure as shown in FIG. Fourthly, as shown in FIGS. 30, 31 and 34, since the structure here adopts the structure in which the control button 24 is used to press the holding belt 13, the friction between the two is mainly achieved by locking the holding belt. Therefore, even if the surface of the grip belt has a smooth structure, as long as the control button can provide sufficient pressure, the grip belt can also be locked, and of course, the rough surface structure of some protrusions or pits can be further improved. The friction between the two can also be used in the form of a mesh or a stripe structure. There are many more structures like the above, and will not be described too much here.

The pits on the grip belt 13 in the present invention are pits or grooves regularly arranged on the grip belt 13, and the pits or grooves therein, as shown in Fig. 38, can be understood as the above ratchet shape. The reverse structure of the rack, that is, the continuously arranged triangular pits, can also function as a ratchet-like rack on the grip belt 13; as shown in FIGS. 30 and 31, it can also be understood as a rough surface, that is, the surface has a rough surface of the uneven surface, or a rough surface having a grain on the surface, the holding tape 13 of the surface is pressed against the surface of the holding tape 13 by the control button 24 when the length adjusting device of the control button 24 is engaged, The locking of the grip 13 belt can be achieved.

The holes in the grip belt 13 in the present invention are through holes or counterbore which are regularly arranged on the grip belt 13. As shown in FIG. 19, the grip belt 13 is provided with a square hole, that is, a telescopic hole 19, which is evenly arranged, and the length adjusting device in the telescopic cavity 14 is also a pawl-shaped limiting tooth 20, which passes through The insertion of the limiting tooth 20 into the above-mentioned telescopic hole 19 can also achieve the locking of the holding strap 13. Naturally, the telescopic hole 19 can be a square hole, a circular hole or a hole of other shapes, and the holes are not only referred to. The hole can be used as well as the counterbore of the above shape as long as the depth satisfies the requirement of the insertion of the limiting tooth 20.

As a core component of the present invention, the length adjusting device is mainly for flexibly adjusting the length of the grip belt 13 to be extended so as to be locked when the proper position is extended, that is, when the thickness of the user's finger is similar. Make it a ring of appropriate length. The length adjusting device needs to be realized by the cooperation of the holding belt 13 and the limiting member in the telescopic chamber 14. The length adjusting device is a limiting member disposed in the telescopic cavity 14 or adjacent to the opening of the telescopic cavity 14 and a holding strap 13 sliding in the telescopic cavity 14. The limiting component is generally installed in the telescopic cavity 14, especially the telescopic Above the opening position of the cavity 14, it is of course also possible to mount the above-mentioned limiting member beside the opening of the telescopic cavity 14, as long as the cooperation with the holding tape 13 can be satisfied. The matching member cooperates with the protrusion or the pit or the hole of the surface of the holding belt 13 to lock the sliding holding belt 13 to cooperate with the holding belt 13 of the above various structures. The limiting member is also a protruding structure similar to a pawl, as shown in Figures 3-6, 15-18 and the like. It may also be a flap that is placed across the open position of the telescopic chamber 14, as shown in FIG. All of the three structures can satisfy the locking of the different structure holding straps 13. The specific cooperation manner will be described in detail in the following specific embodiments with reference to the accompanying drawings.

The limiting member is a core component of the length adjusting device in the present invention, and functions to hold the holding belt 13 at an appropriate position. Line lock. The limiting member is an integral protruding pawl disposed in the telescopic cavity 14 or adjacent to the opening of the telescopic cavity 14 or an integral pit or hole disposed in the telescopic cavity 14 or adjacent to the opening of the telescopic cavity 14, as shown in FIG. 3-6. As shown, the pawl 17 referred to herein is primarily for mating with a grip belt 13 having a ratchet 15 surface, and is engaged with the pawl 17 on the bellows 14 by the ratchet 15 on the grip belt 13 Holding the strap 13, as for the pawl 17, there is also an alternative structure that can achieve the same function. For example, a flat flap can be placed over the opening position of the telescopic cavity 14, and the pawl 17 can also be replaced. The recessed portion of the bellows 14 is provided with a recess that cooperates with the shape of the ratchet 15 and can also be used in conjunction with the grip belt 13, so that the pawl 15 of the present invention also includes some functionally equivalent components. As shown in FIG. 19, the above-mentioned stoppers lock the sliding grip belt 13 by cooperating with the protrusions or the pits or holes on the grip belt 13, through the pawl 17 and the grip belt 13 described above. The regular projections or the recesses or the holes cooperate to lock the gripping belt 13 which slides in the telescopic cavity 14, or are slidably locked in the telescopic cavity 14 by the above-described cooperation of the dimples or holes and the regular projections on the gripping belt 13 Holding tape. As shown in FIG. 15-19, the holding strap 13 is equidistantly disposed with a square through hole, that is, a telescopic hole 19, and a square cylindrical limit corresponding to the square telescopic hole 19 is disposed at an opening position of the telescopic cavity 14. It is also possible to replace the limit tooth 20 in the figure. It should be noted here that the grip belt 13 is preferably made of a material having a certain elasticity and setting ability such as plastic or nylon, because this material property is advantageous for the expansion and contraction operation of the grip belt 13. For example, when the grip belt 13 is pulled out, the plastic or nylon material is required to have certain toughness, and the grip belt 13 is slightly pressed down while the grip belt 13 is pulled out, so that the grip belt 13 is along the telescopic cavity. 14 The bottom surface slides out, so that the locking of the holding strap 13 by the limiting member can be avoided, and when the holding strap 13 is extended to the appropriate position, the holding strap 13 can be lifted up to limit the limiting tooth 20 The positioning member is inserted into the square telescopic hole 19 of the holding belt 13 to realize locking. The other types of holding belts 13 in the present invention are preferably made of plastic or nylon. These materials have certain elasticity and meet the needs of use. toughness. It is of course possible to use the other softer material to make the grip belt 13 which can also be used in the present invention, but its use effect is far less convenient than the use of the above materials.

Next, another type of length adjusting device of the present invention will be described. As shown in Figs. 30-34, the length adjusting device is a control button 24 disposed on the telescopic cavity 14 and a grip for sliding in the telescopic cavity 14. The belt 13 is composed of a lower end of the control button 24 and a surface structure of the holding belt 13. The control button 24 is a liftable button or a switchable cover plate disposed on the telescopic cavity 14, and is lifted and lowered by the above-mentioned control button 24. Or a switch that presses or snaps the grip belt 13 to lock the grip belt 13. First, the structure of the lift button will be described, as shown in Figs. 32 and 33, while referring to Figs. 35 and 36. The control button 24 is disposed in a through hole in the upper sidewall of the telescopic cavity 14. The control button 24 is actually formed by a U-shaped cutout on the upper sidewall of the telescopic cavity 14, and the end is also telescopic The cavity 14 is connected, so that it has a certain elasticity and can be pressed up and down. The thickness of the above-mentioned control button 24 is smaller than the thickness of the side wall of the telescopic cavity 14, so that an under-hole is formed below the button. The grip belt 13 is also provided with a "U" shaped incision at equal distances. The tongue piece 25 formed by the "U" shaped slit is in the raised position. As is apparent from the above structure, when the grip belt 13 slides in the bellows 14, the grip belt 13 is not restricted in the process of retracting into the bellows chamber 14. While the grip belt 13 is in the process of extending, the tongue piece 25 is inserted into the pocket to prevent the grip belt 13 from protruding. This is to press the control button 24 to force the tongue 25 to contract. Back, at this time, the control button 24 just fills the pit, and the grip belt 13 can be arbitrarily slid. When the grip belt 13 is slid to a proper position, after the control button 24 is released, the next tongue 25 is immediately Entering the pocket will lock the grip belt 13. Thus, the extension length of the grip belt 13 can be arbitrarily adjusted. The control button 24 used in the present invention has various other similar functional equivalent components, and is not described too much in view of the common technology. As shown in Figures 30, 31 and 34, the control button 24 of the present invention can adopt a switchable cover structure. The above control button 24 is a switchable cover plate, and the cover plate adopts a common snap structure, that is, The fastening is performed by the mutual engagement between the buckle provided on the cover plate and the side wall of the telescopic cavity 14. The surface of the grip belt 13 has all kinds of structures that can be adopted almost as described above, as long as the bottom shape of the above-mentioned control button 24 can be interlocked to achieve locking, for example, for a grip belt having a ratchet-like surface. 13. At least one ratchet tooth is disposed on the lower surface of the control button 24, and a plurality of corresponding ratchet structures may be disposed at the bottom of the control button 24 to improve the fixing strength of the grip belt 13 and ensure the reliability of the holding device. . In short, in the use of the grip belt 13 of various structures mentioned above, it is only necessary to arrange the stopper at the bottom of the control button 24. However, it should be noted here that, in the case of using the cover structure as the control button 24, the telescopic cavity 14 can be slightly spaced from the grip belt 13. Here, it is necessary to specify the holding belt 13, which is the above-mentioned holding belt 3 having a rough surface, which may be a stripe structure formed by ribs or grooves, or may be a grid. The structure of the shape or the curved line may of course be irregular protrusions and pits to form a rough structure, and the lower part of the control button 24 may have a surface structure corresponding to the surface of the holding belt 13 correspondingly, and the purpose is to be as large as possible. The guarantee of the friction between the two. With the grip belt 13 of the above structure, an interference fit is adopted between the control button 24 and the grip belt 13, that is, after the control button 24 is engaged, sufficient pressure is generated on the grip belt 13 to ensure the second They are in a fixed state. Therefore, when the holding device of this structure is adjusted, the cover plate as the control button 24 is opened, the adjusted cover is fastened, and the holding tape 13 is fixed at an appropriate length. Users who consider mobile phones or other electronic devices are generally fixed by one person, so this adjustment only needs to be done once. Considering the storage problem of the use of the grip belt, the telescopic cavity 14 of the holding device needs to be provided two, but only one of the telescopic cavities 14 is provided with the above-mentioned cover structure control button 24, and the natural grip belt 13 is only required. A length has a rough surface that matches the bottom surface of the control button 24. The other end of the grip belt 13 is free to slide in the other telescopic cavity 14. To prevent the grip belt 14 from coming off, a larger end is required at the end. This end is made larger than the opening of the telescopic chamber 14, thus forming a tamper-proof head 18 that prevents the grip belt 13 from coming off.

Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

As shown in FIG. 1-6, in the first embodiment of the present invention, a mobile phone holding device with a rack-shaped holding strap, the main technical improvement is that the holding device is fixed on the mobile phone body, and is fixed by The seat 12 and the grip belt 13 are composed of two kinds of use manners, one of which is made into a separate component, which is fixed to the mobile phone by bonding or other means, for example, the bottom of the fixed seat 12 is not set. Dry glue bonding layer. The other one is directly integrated with the mobile phone at the time of production, so that the fixed seat 12 is a part of the mobile phone body. As shown in FIG. 5 and FIG. 6, at least one end of the fixing base 12 is provided with a telescopic cavity 14, and the end portion of the holding strap 13 extends into the telescopic cavity 14, and the other end of the holding strap 13 is fixed to the fixing seat. 12 fixed. The fixing of the grip belt is carried out by the snap-in fixing method as shown in Fig. 3-6, and the pin shaft is fixed, and even the fixing seat can be integrally formed. As shown in FIG. 3-6, when the telescopic cavity 14 is disposed at one end or both ends of the fixing base 12, the ratchet 15 is disposed at one end or both ends of the holding strap 13 to be matched, and when the telescopic cavity 14 is disposed at one end, The grip belt 13 has no end of the telescopic cavity 14, and is directly fixed to the fixing base 12. The grip belt 13 is provided with at least one end surface on which one or more ratchet teeth 15 are disposed. The ratchet teeth 15 are disposed in plurality to form a rack-like structure, and the length of the set is determined by the required adjustment range, that is, the thickest and most common. The gap between the finest fingers to ensure that the gripping device can be applied to all people. In order to cooperate with the expansion and contraction of the grip belt 13, the expansion chamber 14 is provided with a pawl 17 which cooperates with the ratchet 15 at the opening position, and the pawl 17 is preferably disposed above the opening of the telescopic chamber 14, so that The degree adjustment is performed in cooperation with the ratchets 15 on the grip belt 13. As shown in FIG. 1 and FIG. 2, in the use process of the present invention, the holding strap 13 is first pulled out with a finger, because the distance between the pawl 17 at the opening of the telescopic cavity 14 and the lower side of the opening is larger than the holding strap. The thickness of 13 is slightly pressed downward when the grip belt 13 is pulled to be brought close to the lower portion of the telescopic cavity 14 to be pulled out. As shown in Figure 1, the grip belt can be pulled out smoothly. When the length is similar to the finger's own finger thickness, the finger can be inserted. As shown in Fig. 3 and Fig. 5, the grip belt is inserted after the finger is inserted. 13 starts to lift upwards, so that the ratchet teeth 15 on the grip belt 13 cooperate with the pawls 17 at the upper portion of the opening of the bellows 14 to lock the length of the grip belt 13. After use, the grip belt 13 is slightly pressed downward to disengage the ratchet teeth 15 and the pawl 17, and the above-mentioned grip belt 13 can be retracted into the telescopic chamber 14. Considering the above-mentioned use requirements, the grip belt 13 is preferably made of a material having a certain toughness because such a material makes it easier to control the disengagement between the ratchet 15 and the pawl 17, for example, plastic, resin, nylon, etc. . Conversely, the use of a relatively soft material to form the gripping strip 13 makes it difficult to control the disengagement between the telescoping aperture ratchet 15 and the pawl 17. When the grip belt 13 of the present invention is used, it actually constitutes a finger ring fixed to the mobile phone, so that a simple grip on the mobile phone can be realized by inserting one finger.

The cavity 11 is closed. In this way, not only can the pressure received by the finger when being held by the finger be significantly reduced, but also the closing of the accommodating cavity 11 by the accommodating cavity cover 16 can be avoided, thereby preventing the above-mentioned holding device from affecting the appearance of the mobile phone. As shown in FIG. 17 and FIG. 18, in addition, in the present invention, there is also a structure in which only one telescopic cavity 14 is provided. At this time, one end of the holding tape 13 is fixed in the accommodating cavity 11, and thus the gripping band 13 is extended. After the outflow, the accommodating cavity cover 16 extended by the body of the holding strap 13 is biased to one side, thereby affecting the comfort of the hand. Therefore, another accommodating cavity cover 16 structure is adopted. The chamber cover 16 is fitted over the grip belt 13 and has a shape that cooperates with the opening of the accommodating chamber 11, and the accommodating chamber cover 16 can slide on the grip belt 13. At this time, the accommodating chamber cover 16 is actually an annular structure fitted on the holding belt 13, but its outer shape is matched with the opening shape of the accommodating chamber 11. By its sliding on the grip belt 13, it is possible to adjust to a position where the user feels comfortable.

As shown in FIG. 13 and FIG. 14 , the function of the accommodating cavity cover 16 is mainly to maintain the overall appearance of the mobile phone. Therefore, the accommodating cavity cover 16 needs to be closely matched with the opening of the accommodating cavity 11 for opening. The chamber cover 16 is placed. The receiving cavity cover 16 is provided with a recess or a protrusion for opening. It is of course preferable to adopt a structure in which a pit is provided, and the accommodating chamber cover 16 can be lifted by inserting a nail into the pit during use. Of course, the above-mentioned pits can also be arranged beside the opening of the accommodating chamber as shown in FIG.

In order to prevent the grip belt 13 from completely falling out of the telescopic chamber 14, the opening of the telescopic chamber 14 is smaller than the inner dimension of the cavity, and the end of the grip belt 13 is provided with a retaining head 18 larger than the opening of the telescopic chamber 14. This can completely avoid holding The belt is detached from the telescopic chamber 14.

As shown in FIG. 22 to FIG. 25, in a fourth embodiment of the present invention, that is, a mobile phone holding device with a chain-shaped holding strap, the main technical improvement is that the holding device is fixed on the mobile phone body, The fixing seat 12 with the accommodating cavity 11 and the holding belt 13 are used. The holding device has two ways of using one. The first one is made into a separate component, and is fixed to the mobile phone by bonding or other means, for example. : Set a self-adhesive bonding layer on the bottom of the holder. The other is to be integrated with the mobile phone directly at the time of production, so that the fixed seat 13 is part of the mobile phone. The receiving cavity 11 is provided with a telescopic cavity 14 at least one end thereof, and the end portion of the holding strap 13 extends into the telescopic cavity 14, and at least one end of the holding strap 13 is disposed in the telescopic cavity 14 to accommodate one end of the cavity 11 or When the telescopic cavity 14 is disposed at both ends, a chain composed of the links 22 is necessarily provided for the one end or both ends of the holding strap 13 to be matched. As shown in Figure 5. When the structure of the telescopic cavity 14 is provided at one end, the grip tape 13 has no end of the telescopic cavity 14, and is directly fixed in the accommodating cavity 11. The holding strap 13 is provided with a receiving cavity cover 16 and is fastened on the accommodating cavity 11. The accommodating cavity cover 16 is actually extended by the body of the holding strap 13, mainly for holding the strap 13 more. The width is wide, thereby improving the comfort of use, and at the same time, when the holding device is not used, the accommodating cavity 11 is closed to keep the appearance of the mobile phone flat and beautiful. As shown in Figs. 24 and 25, the grip belt 13 has at least one end formed of a chain of one or more links 22. It should be noted here that the chain-like structure is quite different from the chain seen. The chain in the present invention mainly refers to the fixed connection of several sections of the links using pins, and the cross-sectional shape of the connection is not More limited, rectangular, flat oval, etc., its structure is more similar to the metal watch chain. In actual use, these links 22 form a chain-like structure, and the length of the chain setting is determined by the required adjustment range, that is, the gap between the thickest and the thinnest fingers of the ordinary person, so as to ensure that the holding device can be applied to all crowd. In order to cooperate with the expansion and contraction of the grip belt 13, the opening portion of the telescopic cavity 14 is provided with a limiting hole 23 which cooperates with the cross section of the link 22, and the limiting hole 23 is a section of the opening of the telescopic cavity and a section of the link. In order to ensure the reliability of the positioning of the link 22 in the limiting hole 23, the length of the limiting hole 23 is not less than half of the length of the link 22 to ensure that the link 22 does not protrude in the limiting hole 23. Shake. It should be noted that a section of the opening of the telescopic cavity 14 is to be matched with the section of the link 22, and the gap between the two is minimized under the premise of ensuring the normal expansion and contraction of the link 22, that is, the manner of small clearance fit. The grip belt 13 is telescopically slidable in the telescopic chamber 14. When in use, when the grip belt 13 is pulled out to a certain link 12 position, the finger is inserted into the finger ring formed by the grip belt 13, and the grip belt 13 will remain in the limit hole 23 at this time. The link 22 generates an upward pulling force, and the segment 22 is located in the limiting hole 23 that fits the outer shape thereof, so that the length of the holding band 13 is reliably limited to this length. This description is known. Here, the chain itself and the bellows opening that cooperates with the small gap constitute the length adjusting device described above.

As shown in FIG. 20 and FIG. 21, in the use process of the present invention, the accommodating chamber cover 16 formed by the body of the holding belt 13 is first opened by a finger, and then the holding belt 13 is pulled out along the axial direction of the telescopic chamber 14. Because the limit hole 23 is slightly larger than the chain link The size of 22 is as shown in Fig. 20, so that the grip belt 13 can be smoothly pulled out, and can be used by inserting a finger when pulled to a length similar to the thickness of the finger of the finger itself, as shown in Fig. 22 and Fig. 24, due to the insertion. The finger grip belt 13 is initially lifted upward, so that the grip belt 13 has an upward pulling force on the link 23 which is still in the limiting hole 22, and the direction of the pulling force is close to the axis of the limiting hole 23. In the direction, the segment 22 will have a tendency to oscillate up and down, and the link 22 is again restrained in the limiting hole 23, so that the link 22 is tensioned and fixed in the limiting hole 23 by the pulling force. After the use is completed, the grip belt 13 is retracted in the axial direction of the stopper hole 23, and the above-mentioned grip belt 13 can be retracted into the telescopic chamber 14. In consideration of the above-mentioned use requirements, the grip belt is preferably made of a material having strength to ensure that the grip belt 13 has sufficient use strength. When the grip belt 13 of the present invention is used, it actually constitutes a finger ring fixed to the mobile phone, so that a simple grip on the mobile phone can be realized by inserting one finger. The invention can improve the reliability of holding the mobile phone, and more importantly, can save two out of the finger to participate in the dry operation of the mobile phone screen, compared with the existing palm rest using the mobile phone, at least five centimeters can be extended. The scope of operation. Full-screen control of touch-screen phones with five-inch or even six-inch screens is easy.

As shown in FIG. 21 and FIG. 23, in order to improve the comfort of the present invention during operation, the accommodating chamber cover 16 is formed by the body of the holding belt 13 and is matched with the opening of the accommodating chamber 11, and the above-mentioned capacity is The cavity 11 is closed. In this way, not only can the pressure received by the finger when being held by the finger be significantly reduced, but also the closing of the accommodating cavity 11 by the accommodating cavity cover 16 can be avoided, thereby preventing the above-mentioned holding device from affecting the appearance of the mobile phone. As shown in FIG. 24 and FIG. 25, in addition, in the present invention, there is also a structure in which only one telescopic cavity 14 is provided. At this time, one end of the holding strap 13 is fixed in the accommodating cavity 11, and thus the gripping band 13 is extended. After that, the accommodating cavity cover 16 extended by the body of the holding strap 13 has a position which is biased to one side, thereby affecting the comfort of the hand. Therefore, another accommodating cavity cover 16 structure is adopted. The chamber cover 16 is fitted over the grip belt 13 and has a shape that cooperates with the opening of the accommodating chamber 11, and the accommodating chamber cover 16 can slide on the grip belt 13. The accommodating chamber cover 16 at this time is actually an annular outer casing fitted on the holding belt 13, but its outer shape is matched with the opening shape of the accommodating chamber 11. By its sliding on the grip belt 13, it is possible to adjust to a position where the user feels comfortable. This arrangement has two advantages, one of which can widen the middle of the grip belt 13, so that the finger can reduce the force of the finger while holding the hand-held machine or other electronic devices, and at the same time, the finger holding is also improved to some extent. Hold reliability.
