Abstract

The invention relates to a stand for a hand-held device and a protective case comprising the stand. The stand comprises a first plate, a second plate, a first elastic piece, a second elastic piece and a limiting device. The first ends of the first elastic piece and the second elastic piece are respectively arranged on the two sides of the first plate. The limiting device enables the second end of the first plate and the second end of the second plate to slide and rotate within a limited range. When the second end of the first elastic piece and the second end of the second elastic piece depart from each other, the first plate forms a vertical displacement relative to the second plate. When the second end of the first elastic piece and the second end of the second elastic piece rotate about a first axle and a second axle, respectively, the first plate forms a transverse offset relative to the second plate owing to the first and second elastic pieces being twisted.

Description

Stand for a handheld device and protective case including the stand

The invention relates to a stand for a hand-held device, in particular to a collapsible stand with a changeable support angle.

Most of the existing handheld devices have rich entertainment functions, such as: audio and video playback, e-book reading and electronic games, etc. Therefore, users often need to use the handheld device continuously, and sometimes need to use it as a banner to get closer to normal The aspect ratio of the screen. However, due to the flat shape of the handheld device, it does not conform to the ergonomics of the hand at all, and the handheld device will often be accidentally dropped and damaged due to various reasons (such as sore hands, too little friction, lack of concentration, etc.). In addition, when watching movies or videos, if you don’t want to hold it for a long time, you must have something against your back, or put it on an extra bracket or tripod, which will cause problems such as inappropriate viewing angles. quite inconvenient.

Therefore, some people began to propose technical means to solve the above problems, attaching a simple foldable stand to the back of the mobile phone, which can be directly pasted on the back shell of the bare phone, or on the protective case, or directly connected The shell is made in one piece, so that users can directly purchase products with a stand when purchasing a protective shell. The foldable "ring" type of this kind of stand is the most popular, but because the overall area of the ring type is small, the position of the mobile phone must be able to allow the user's dominant finger A good position to pass through and hold the phone at the same time, so that the phone does not fall, and this good position is usually not the best position to support the phone at a suitable viewing angle, or even support the phone to make it stand, let alone use in Larger-sized tablet electronic devices do not have the flexibility to match mobile phones or tablets horizontally or vertically; that is to say, the "ring"-style stand is too small to prevent falling and perfectly support the mobile phone. Between mobile phones, it is usually impossible to have the best of both worlds. Moreover, the "ring" is usually made of metal, and it needs to be closed by a rotating shaft. The thickness of the overall structure cannot be simplified, and the shape is irregular and asymmetrical. Overall, it is not beautiful. When it is not in use, unless there are other auxiliary mechanisms , the mobile phone cannot lie flat on the table like a bare phone. Overall, it is still a very bad design.

In addition to the early "ring" design, the industry later converted to other methods, such as the "push" type shown in CN305843674S and CN305381641S patents, which are fixed at one end by a soft strip, and a button is provided at the other end, so that the button moves along the Sliding on a track, the soft strip arches like the body of a caterpillar, forming an "Ω" shape, so that it can pass through the fingers and also achieve the function of supporting the mobile phone. However, this design is just another variation of the ring type. Except for the different materials, it is slightly more comfortable to pass through the fingers than the metal ring. The other conditions are the same as the ring type, and the progress is limited.

Although, recently, some industry players have tried to break through the barriers of the ring shape and design other stands that are compatible with storing credit cards. For example, a stand product of the Korean SlashGo brand uses a belt staggered design to try to bridge the gap between the past and the stand. However, the use of "opening and closing" is obviously sloppy, not concise and neat, and leather products are not rigid enough, not resistant to dirt and humidity, etc., which are still a niche in the market. Products cannot be popularized.

In view of this, a stand that can be folded is provided, regardless of whether it is attached to the back of the mobile phone After being attached to the surface of the back shell of the mobile phone, in the use state, it can obtain good support and adjust the placement angle of the mobile phone or a larger tablet, and in the folded state, it can also Being able to maintain the smallest and most uniform protrusion size without hindering the appearance of the original machine has become an urgent research and development goal for the industry. It would be more perfect if this foldable stand had some functions for adjusting the supporting angle.

The main purpose of the present invention is to provide a stand for supporting a hand-held device, the stand includes a first base plate and a second base plate, by means of a lifting device arranged between the first base plate and a second base plate, The first bottom plate is raised and lowered relative to the second bottom plate, wherein the lifting device includes a limiting device. During the lifting process of the first bottom plate and the second bottom plate, the limiting device can limit the lifting of the first bottom plate relative to the second bottom plate to a first bottom plate. until a vertical dead point, and descend to a second vertical dead point closest to the second bottom plate. When the first bottom plate is raised relative to the second bottom plate to the first vertical dead point, the first bottom plate can be laterally offset relative to the second bottom plate to a lateral dead point.

The secondary object of the present invention is to provide a stand for supporting a hand-held device, wherein the position-limiting device guides an end region of a first elastic piece and an end region of a second elastic piece, and is suitable for The second bottom plate moves along a length direction of the second bottom plate within a limited range; when the end regions of the first elastic sheet and the end regions of the second elastic sheet are far away from each other, the first bottom plate and the second elastic sheet can be moved in unison. The bottom plate moves away from each other to a limit and then stops in a direction perpendicular to the first bottom plate; the end area of the first elastic piece and the end area of the second elastic piece are suitable to respectively revolve around a first rotating shaft and a second The rotating shaft rotates at an angle in the opposite direction, so that the first elastic piece and the second elastic piece are twisted, so that the first bottom plate can laterally offset a distance and an angle relative to the second bottom plate.

Another object of the present invention is to provide a mobile phone case installed on the back of a handheld device, the mobile phone case includes the above-mentioned stand.

Before or when being blocked by the first rotating shaft 153 and the second rotating shaft 154, the second end region 1312 of the first elastic piece 131 and the second end region 1322 of the second elastic piece 132 are suitable for respectively bearing force And around the first rotating shaft 153 and the second rotating shaft 154, rotate in the first rotating space 141 and the second rotating space 142 at an angle, so that the first base 11 generates a lateral offset relative to the second base 12, such as 1E, 1F and 1G, in order to further change the relative positional relationship between the first base 11 and the second base 12, so that it is not limited to a substantially parallel relationship, but becomes non-parallel, or even produces a misalignment angle, thereby increasing the number of handheld devices The stand or use angle changes, and further, as shown in Figure 1G, when the first base 11 is relative to the second base After the seat 12 is laterally shifted, the first base 11 and the second base 12 have an included angle a, the included angle a is preferably between 15-80 degrees, so that the handheld device is placed on the first base 11 or The second base 12 can assume an inclined posture to provide a more flexible viewing angle for users to watch.

Based on the above description, the present invention actually provides a limiting device, so that two opposite linear elastic pieces arranged between two parallel bases slide within a limited range, so that they are deformed during the sliding period. The bending is arc-shaped, thus causing a vertical displacement of the two bases, so that a first open state can be achieved. The limiting device also includes a rotating device, whereby the two curved elastic pieces can be twisted in opposite directions within a limited range, so that they are deformed again during the twisting period, so that one base generates a transverse direction to the other base. Offset to reach a second open state, so as to increase the flexibility of use. In short, the two elastic pieces can open the stand through the process of first sliding and then twisting, and reversely through the process of first twisting and then sliding to close the stand. The detailed structure capable of achieving the above actions is further described as follows.

In detail, the first base 11 includes a first bottom plate 111 , and the second base 12 includes a second bottom plate 121 opposite to the first bottom plate 111 . The stand 10 further includes a lifting device 13 disposed between the first bottom plate 111 and the second bottom plate 121 , and the lifting device 13 includes a first elastic piece 131 , a second elastic piece 132 and a limiting device 133 . The first end region 1311 of the first elastic piece 131 is disposed on the first region 1111 of the first bottom plate 111 . The first end region 1321 of the second elastic piece 132 is disposed on the second region 1112 of the first bottom plate 111 . Preferably, the first area 1111 is inside one end of the first bottom plate, and the second area 1112 is inside the other opposite end of the first bottom plate 111 .

The limiting device 133 includes two side walls 143 , 144 , a first bridge 145 , a first slide slot 146 , a second bridge 147 and a second slide slot 148 . The two side walls 143, 144 are longitudinally arranged on two opposite sides of the second bottom plate 121, and form the above-mentioned sliding space with the second bottom plate 121 14. The first bridge 145 spans over the two side walls 143 and 144 on one side of the second bottom plate 121 , so that the first elastic piece 131 can enter the sliding space 14 from the first bridge 145 . The first sliding groove 146 is disposed in a lengthwise direction of the first elastic piece 131 . The second bridge 147 spans over the two side walls 143 , 144 on the other side of the second bottom plate 121 , so that the second elastic piece 132 can enter the sliding space 14 from under the second bridge 147 . The second sliding slot 148 is disposed in a longitudinal direction of the second elastic piece 132 .

The stop device 133 guides the second end region 1312 of the first elastic piece 131 and the second end region 1322 of the second elastic piece 132, which are suitable for moving along the longitudinal direction of the second bottom plate 121 and away from each other to a first A longitudinal extreme 1461 and a second longitudinal extreme 1481 are used to move the first bottom plate 111 to produce a vertical displacement D1 relative to the second bottom plate 121; wherein the first longitudinal extreme 1461 and the second longitudinal extreme 1481 are respectively one end of the first chute 146 And defined by one end of the second chute 148 . The first rotating shaft 153 is arranged under the first span bridge 145 and passes through the first chute 146, so that the first elastic piece 131 is limited to slide along the first chute 146, and the first rotating shaft 153 does not protrude from the second bottom plate One outer surface 1211 of 121; The second rotating shaft 154 is located under the second bridge 147 and passes through the second chute 148 so that the second elastic sheet 132 is limited to slide along the second chute 148, and the second rotating shaft 154 does not protrude from the outer surface 1211 of the second base plate 121 to maintain the flatness of the second base plate 121 and will not affect the appearance and stability of the second base plate 121 attached to other accessories, such as the back plate of the handheld device.

Referring to Fig. 1A, 1B, 1C continuously, the first elastic sheet 131 and the second elastic sheet 132 are linear, when the second end area 1312 of the first elastic sheet 131 and the second end area of the second elastic sheet 132 When 1322 are away from each other, the first elastic piece 131 and the second elastic piece 132 are gradually elastically deformed into an arc shape, so as to increase the vertical displacement D1; when the second end region 1312 of the first elastic piece 131 and the second elastic piece 132 When the second end regions 1322 approach each other, the first elastic piece 131 and the second elastic piece 132 gradually return to the original linear shape, so as to reduce the vertical displacement D1. One of the first elastic sheet 131 and the second elastic sheet 132, the length of which is no longer than that of the first bottom One-half of the length of the plate 111. More preferably, the lengths of the first elastic piece 131 and the second elastic piece 132 are substantially the same, and are not greater than 1/2 of the length of the first bottom plate 111; when the second end region 1312 of the first elastic piece 131 and the second The second end region 1322 of the elastic piece 132 is far away from each other, and when the first rotating shaft 153 and the second rotating shaft 154 are respectively stopped by the first longitudinal extreme 1461 and the second longitudinal extreme 1481, the vertical displacement D1 is the largest, as shown in FIG. 1C Show; When the second end region 1312 of the first elastic sheet 131 is closest to the second end region 1322 of the second elastic sheet 132, the first bottom plate 111 and the second bottom plate 121 can be superimposed on each other, as shown in Figure 1A As shown; more preferably, when the first base 11 and the second base 12 overlap each other, the second end area 1312 of the first elastic sheet 131 and the second end area 1322 of the second elastic sheet 132 can be against each other Sliding is stopped by relying on it, so as to avoid the phenomenon of "slipping" along the length direction of the first base 11 and the second base 12.

The two side walls 143, 144 extend outward from the two longitudinal ends of the second bottom plate 121, respectively, to form two first lateral extremes and two second lateral extremes. , so that the first rotating space 141 and the second rotating space 142 are formed on the outer sides of the first spanning bridge 145 and the second spanning bridge 147 and expand outwards in the longitudinal direction, respectively. When the first longitudinal extreme 1461 abuts (or is about to abut) the first shaft 153, and the second longitudinal extreme 1481 abuts (or is about to abut) the second shaft 154, that is, the stand 10 is fully opened (or almost completely) When in the state of opening), the second end region 1312 of the first elastic piece 131 and the second end region 1322 of the second elastic piece 132 can further rotate in opposite directions around the first rotating shaft 153 and the second rotating shaft 154 respectively. (one is counterclockwise, the other is clockwise), rotate to the first lateral extreme (defined by one of the first slanted side walls 1431) and the second lateral extreme (defined by the other first slanted side wall 1431) defined) and stop, so that both the first elastic piece 131 and the second elastic piece 132 are twisted, and the first bottom plate 111 generates the above-mentioned lateral offset relative to the second bottom plate 121, as shown in Figures 1E, 1G, and 1H. And the above-mentioned figure shows the embodiment with two pairs of oblique sidewalls 1431 and 1441, optional Choose to make the first bottom plate 111 produce a bidirectional lateral offset toward the first inclined side wall 1431 or the second inclined side wall 1441 relative to the second bottom plate 121; in practice, only one pair of inclined side walls can be provided (For example, the first slanted side wall 1431), it is also feasible to make the first bottom plate 111 relative to the second bottom plate 121 produce a lateral offset in only one direction towards the first slanted side wall 1431; but because the concept of change is easy to understand, It is no longer represented graphically.

In order to improve the operation stability and product reliability of the stand 10, especially the feel when the first base 11 is vertically raised relative to the second base 12, and the first base 11 is laterally offset relative to the second base 12. At the end point, the solid feeling of the entire movement that can be stably stopped will depend on the second end area 1312 of the first elastic piece 131 and the second end area 1322 of the second elastic piece 132 in the sliding space 14, the first rotating space 141 and the second end area 1322. Whether the movement of the second rotating space 142 is correct. Therefore, a simple mechanism can be installed on the limit device to achieve the above purpose. Now, the bottom perspective view of Figure 2A, 2B and 2C is used to illustrate (the diagrams from other angles are not different because there is no difference), and the numbers are also quoted. Figure 1 series for simplicity.

In other words, the second base 12 further includes two first protrusions 21a, 21b and two second protrusions 22a, 22b. The risers 22a and 22b are disposed on two sides of the second rotating shaft 154 . Preferably, the two first protrusions 21a, 21b slightly extend downward from the first bridge 145, and the extent of extension substantially overlaps with the thickness of the first elastic sheet 131; and the two second protrusions 22a, 22b, Extend slightly downward from the second span bridge 147, and the extent of extension substantially overlaps with the thickness of the second elastic sheet 132, so that when the second end region 1312 of the first elastic sheet 131 and the second end region 1312 of the second elastic sheet 132 When the end region 1322 moves in the sliding space 14, it is also limited laterally by the two first protrusions 21a, 21b, and the range defined by the two second protrusions 22a, 22b, as shown in Figures 2A and 2B; The second end region 1312 of the first elastic piece 131 and the second end region 1322 of the second elastic piece 132 respectively reach a first longitudinal extreme 1461 and a second longitudinal extreme 1481, and when it can rotate in the first rotating space 141 and the second rotating space 142, the second end region 1312 of the first elastic piece 131 can cover the first protrusion 21b, and The first protrusion 21b vertically overlaps and closely contacts, and the second end region 1322 of the second elastic piece 132 is suitable to cover the second protrusion 22b, and vertically overlaps and closely contacts the second protrusion 22b. At this time, since the second end regions 1312, 1322 generate a certain degree of frictional force with the first protrusion 21b and the second protrusion 22b respectively, it can slightly help maintain the first elastic piece 131 and the second elastic piece 132 after being twisted. state, so that the first base 11 and the second base 12 maintain a laterally offset positional relationship, as shown in FIG. clear its position), until the user needs to fold the stand 10, again overcome the friction between the first elastic piece 131 and the first protrusion 21b, and the friction between the second elastic piece 132 and the second protrusion 22b, and leave the first The vertical extreme 1461 and the second vertical extreme 1481 carry out the procedure of returning and folding.

In practical applications, the stand 10 can utilize an outer surface (such as the outer surface 1211) of one of the first base 11 and the second base 12 to install an attachment device (not shown), such as glue, double Surface glue, re-pastable PU glue or magnetic attraction devices, such as general magnets, rubber magnets or strong Nd-Fe-B magnets, etc., and the back plate 30 of the handheld device 3 or the back plate of the protective case 4 40, in a temporary or permanent connection, as shown in Fig. 3 or Fig. 4 . The stand 10 can also be directly embedded in the back plate 50 of the protective case 5 or integrally formed with the back plate 50 as a part of the protective case 5 to form a protective case with a stand to further increase the functionality of the product For example, the backboard 50 is formed as one with the second bottom plate, two side walls, and the bridge; Structurally, the backboard 50 serves as the two side walls 143,144 of the stand 10 shown in Figure 1E, the first bridge 145 and the second bridge Two bridges 147, and the back plate 50 can add an inner liner 51 again, as the second base plate 121 of the stand 10, as shown in Figure 5; certainly also can directly use the back plate 30 of the handheld device 3 of Figure 3, As the second bottom plate 121 of the stand 10 .

Similarly, if one of the first base 11 and the second base 12 has been connected to the handheld The back plate 30 of the device 3 or the back plate 40 of the protective case 4, the outer surface of the other can be added in a similar manner with an attachment device (not shown), such as a magnet, or directly use a magnetic material itself for temporary attachment. It is attached to a support frame (not shown) that can be matched with it, and the support frame is, for example, a bracket that is clamped on the air-conditioning outlet in the car or on the instrument panel. The above is used to exemplify the preferred embodiments supporting the core technology of the present invention, in order to explain the technical characteristics of the present invention, not to limit the technical means of the present invention. In fact, the present invention mainly provides a means for supporting a handheld device, which includes a lifting means for lifting a first base relative to a second base. The lifting means further includes a guiding means for guiding the first base relative to the second base to rise to a first vertical dead point and to descend to a second vertical dead point. The guiding means (means) also includes: an offset means (means), when the first base is raised to the first vertical dead point relative to the second base, the offset means is used to make the first base A base is offset laterally relative to the second base up to a lateral dead point. In addition to the detailed descriptions of the structures, materials, and modes of operation of these means in the above-mentioned embodiments, the following additionally lists the possible transformation styles to clarify the scope of equality, but it still does not limit the application for patents in the next paragraph. Range claimant:

1. The first elastic piece and the second elastic piece can be of different sizes, different materials, and placed in different positions. The two do not necessarily have to be symmetrical to each other. In terms of operation, the first elastic piece and the second elastic piece are located on both sides Nor does it necessarily require symmetrical lifts. The first elastic piece and the second elastic piece are individually arranged so that their actions do not overlap each other. The main purpose is to make the size of the stand more flexible as needed, so that it can be installed on a larger-sized handheld device .

2. In order to make the product operation more stable and reliable during the period from folding to unfolding of the stand, the preferred thickness of the first elastic sheet and the second elastic sheet is 0.08mm to 2mm, more preferably 0.2mm to 1.0mm; The materials used for the first elastic sheet and the second elastic sheet are not restricted, they can be metal, Plastic or various forms of composite materials, if it is made of plastic, its preferred elastic modulus (Elasticity Module, Gpa) is between 1Gpa and 5Gpa, if it is made of metal, its preferred elastic modulus is between 70Gpa and 195Gpa .

3. Because the first elastic piece and the second elastic piece have an elastic recovery force that returns to a straight line, therefore, when the stand is opened vertically, the second end region will generate a maximum vertical thrust to the second bottom plate, The stand tends to stop in the vertically open state, forming an obvious sense of operation; when the elastic piece is twisted (that is, when the second end area rotates around the axis of rotation), the pushing force still exists, which is enough to support the elastic piece. The process of twisting is stable. If there is a protrusion, the protrusion will rub against the second end region, and the process of twisting the elastic piece will be more stable, unless the user exerts enough operating force to overcome it and make it enter another state. And when the stand is fully folded, because the elastic sheet has returned to its original straight shape, it will naturally tend to the closed state, forming another obvious sense of operation. Of course, since the elastic sheet is guided by the limiting device, there is a specific friction force with other contacted elements, such as the second bottom plate, side wall, bridge, rotating shaft, etc.; therefore, in terms of design, the elastic sheet can also be appropriately increased The friction force between the contact elements makes it stop anywhere during the operation, so that the lifting of the first bottom plate relative to the second bottom plate can achieve the effect of stopping immediately.
