Description

Handwriting pen limiting support and mobile terminal

Technical Field

Background

With the gradual rise of mobile office demands, mobile terminals with handwriting pens are more favored by users due to their convenience. At present, most of flat plates are light and thin, and a handwriting pen is fixed on a flat plate frame in a magnetic attraction mode, and mobile terminals such as mobile phones still limit and fix the handwriting pen in a mode of forming a pen slot in a machine body for inserting the handwriting pen.

In the related art, mobile terminals such as mobile phones and the like typically use a handwriting pen buckle to limit and fix the handwriting pen, as shown in fig. 1, the handwriting pen buckle 01 is generally a small structural member that can be detached separately, and as shown in fig. 2, the handwriting pen buckle 01 can be directly installed in a bayonet slot on the slot wall of the pen slot 02 during assembly. As shown in fig. 1, the handwriting pen buckle 01 comprises an elastic arm 011 and a buckling position 012 arranged on the elastic arm 011, when the handwriting pen is inserted into the pen slot 02, the buckling position 012 can be in surface contact with a limit slot on the handwriting pen and form a back buckle so as to limit and fix the handwriting pen.

Because the pen slot is almost made of metal materials, the pen slot is scratched with the pen slot made of metal materials in the process of inserting and pulling the handwriting pen, so that the handwriting pen is paint-removed, and poor appearance is caused. To avoid this problem, in the related art, the gap between the wall of the pen slot and the stylus is usually enlarged, as shown in fig. 2, and a plastic supporting convex hull 03 with a semicircular cross section is formed by local injection molding in the pen slot 02, and the gap between the plastic supporting convex hull 03 and the stylus is smaller, so that the stylus can be supported, and the stylus body is prevented from tilting and scratching the metal of the body when the stylus is inserted and pulled.

Because the groove wall of the pen groove is provided with the buckle groove for the handwriting pen to be buckled and installed, and the pen groove is formed by die casting of metal materials, the die for die casting is also provided with a groove die casting structure for die casting the buckle groove. And because the plastic supporting convex hulls are formed by injection molding through the mold, the mold is also provided with a convex hull injection molding structure for injection molding the plastic supporting convex hulls. However, the slot die casting structure and the convex hull injection structure can lead to the complex structure of the die, and the more complex the die structure is, the more difficult the dimensional accuracy of the die is to be controlled, and the process yield is also easily reduced.

As described in the background art of the present application, in the related art, a mobile terminal such as a mobile phone uses a handwriting pen buckle to limit and fix a handwriting pen, as shown in fig. 1, the handwriting pen buckle 01 is generally a small structural member that can be detached separately, and as shown in fig. 2, the handwriting pen buckle 01 can be directly installed in a bayonet slot on the slot wall of the pen slot 02 during assembly. As shown in fig. 1, the handwriting pen buckle 01 comprises an elastic arm 011 and a buckling position 012 arranged on the elastic arm 011, when the handwriting pen is inserted into the pen slot 02, the buckling position 012 can be in surface contact with a limit slot on the handwriting pen and form a back buckle so as to limit and fix the handwriting pen.

Because the pen slot is almost made of metal materials, the pen slot is scratched with the pen slot made of metal materials in the process of inserting and pulling the handwriting pen, so that the handwriting pen is paint-removed, and poor appearance is caused. To avoid this problem, in the related art, the gap between the wall of the pen slot and the stylus is usually enlarged, as shown in fig. 2, and a plastic supporting convex hull 03 with a semicircular cross section is formed by local injection molding in the pen slot 02, and the gap between the plastic supporting convex hull 03 and the stylus is smaller, so that the stylus can be supported, and the stylus body is prevented from tilting and scratching the metal of the body when the stylus is inserted and pulled.

Because the groove wall of the pen groove is provided with the buckle groove for the handwriting pen to be buckled and installed, and the pen groove is formed by die casting of metal materials, the die for die casting is also provided with a groove die casting structure for die casting the buckle groove. And because the plastic supporting convex hulls are formed by injection molding through the mold, the mold is also provided with a convex hull injection molding structure for injection molding the plastic supporting convex hulls. However, the slot die casting structure and the convex hull injection structure can lead to the complex structure of the die, and the more complex the die structure is, the more difficult the dimensional accuracy of the die is to be controlled, and the process yield is also easily reduced.

Example 1

In view of the above-mentioned problems, the present application provides a handwriting pen limiting bracket, so as to solve the problem in the related art that the structure of the die casting mold is complex due to the slot die casting structure and the convex hull injection structure.

The technical scheme of the application is further described below with reference to specific embodiments and attached drawings:

As shown in fig. 3 and 4, the stylus limit bracket 10 includes a fixing portion 1 and a soft rubber portion 2. The fixing portion 1 is configured to be disposed in the pen slot 20, the flexible glue portion 2 is disposed in the fixing portion 1, and the flexible glue portion 2 includes an embedding portion 21, where the embedding portion 21 is configured to be embedded in a limit slot 301 (shown in fig. 8 and 9) on the stylus 30 after the stylus 30 is inserted into the pen slot 20 in a forward direction (an X1 direction in fig. 8) of the first direction.

The insertion portion 21 has a limiting surface 211 (shown in fig. 9) having a shape adapted to the shape of the groove wall of the limiting groove 301, and the limiting surface 211 is used to contact the groove wall surface of the limiting groove 301 when the insertion portion 21 is inserted into the limiting groove 301, so as to limit and support the stylus 30.

In the application, since the embedded part 21 of the soft rubber part 2 is provided with the limiting surface 211 with the shape matched with the shape of the groove wall of the limiting groove 301, and the limiting surface 211 is used for being contacted with the groove wall surface of the limiting groove 301 when the embedded part 21 is embedded into the limiting groove 301, the application can not only prevent the handwriting pen 30 from being scratched by the handwriting pen limiting bracket 10 through the soft rubber part 2 in the process of inserting and extracting the handwriting pen 30, but also realize the limiting and supporting of the handwriting pen 30 through the surface contact of the limiting surface 211 and the groove wall surface of the limiting groove 301 after the handwriting pen 30 is inserted into the handwriting pen 20, namely, the handwriting pen limiting bracket 10 can realize the limiting and supporting functions simultaneously through the soft rubber part 2, compared with the prior art, two handwriting pen buckles and plastic supporting convex hulls which respectively realize the limiting and supporting functions are not needed to be arranged in the handwriting pen groove 20, and two unification of the limiting and supporting functions of the handwriting pen buckles and the plastic supporting convex hulls can be realized only by arranging one handwriting pen limiting bracket 10 in the handwriting pen groove 20.

Because only one handwriting pen limiting bracket 10 is required to be arranged in the pen slot 20 in the application, when the handwriting pen limiting bracket 10 is arranged in the pen slot 20 through the groove on the wall of the pen slot 20, the die of the die casting pen slot only needs to be provided with a groove die casting structure for die casting the groove, and the injection structure in the related art is not required to be arranged, so that the structure of the die can be simplified to a certain extent, the control of the dimensional accuracy of the die is facilitated, and the improvement of the process yield is facilitated. When the handwriting pen limiting support 10 is integrally formed in the pen slot 20 through the die casting of the die casting pen slot 20, the die is only required to be provided with a corresponding injection molding structure, and a slot casting structure in the related art is not required to be arranged, so that the structure of the die can be simplified to a certain extent, the control of the dimensional accuracy of the die is also facilitated, and the improvement of the process yield is also facilitated.

According to the application, the handwriting pen limiting bracket 10 capable of realizing the limiting and supporting functions is arranged, so that the structure of the die can be simplified to a certain extent, the control of the dimensional accuracy of the die is facilitated, and the improvement of the process yield is facilitated.

Further, the fixing portion 1 is a hard rubber portion, and the hard rubber portion and the soft rubber portion 2 form a two-color injection molded body.

Because can reduce the secondary processing of the injection molding body through the bicolor injection molding, consequently bicolor injection molding fixed part 1 and soft rubber part 2 can reduce the secondary processing of both, and then can reduce processing cost, bicolor injection molding fixed part 1 and soft rubber part 2 simultaneously can also make the connection quality between the two higher, and joint strength is stronger.

In other embodiments, the hard rubber part and the soft rubber part 2 can be integrated by insert injection molding. By insert molding, an unnecessary connection process between the fixing portion 1 and the soft rubber portion 2 can be avoided, and the assembly time and cost between the fixing portion 1 and the soft rubber portion 2 can be shortened to some extent.

For the fixing portion 1, in another embodiment, the fixing portion 1 may also be a metal piece. By arranging the handwriting practicing limiting bracket 10 in the pen slot 20 as the fixing portion 1 of the metal member, the stability of the handwriting practicing limiting bracket 10 in the pen slot 20 can be enhanced to some extent.

In yet another embodiment, the fixing portion 1 may also be a soft rubber member integrally injection-molded with the soft rubber portion 2. The fixing part 1 as the soft rubber part is formed by integral injection molding with the soft rubber part 2, so that the manufacturing process of the handwriting pen limiting bracket 10 can be simplified to a certain extent, and the handwriting pen limiting bracket 10 is convenient to process and manufacture.

Further, as shown in fig. 3, a glue pulling groove 11 is formed on one side of the fixing portion 1 away from the soft glue portion 2, and a glue pulling hole 12 communicated with the glue pulling groove 11 is further formed on the fixing portion 1.

As shown in fig. 2 and 4, the flexible glue portion 2 further includes a connection section 22 penetrating through the glue pulling hole 12 and a stop portion 23 disposed in the glue pulling groove 11, one end of the connection section 22 is connected to the embedded portion 21, the other end is connected to the stop portion 23, and the stop portion 23 is in stop fit with a groove wall of the glue pulling groove 11 to fix the flexible glue portion 2 to the fixing portion 1.

Since the stop part 23 and the embedded part 21 connected with the two ends of the connecting section 22 are respectively arranged at the two sides of the fixed part 1, the soft rubber part 2 can be more reliably fixed on the fixed part 1 through the stop fit of the stop part 23 and the groove wall of the rubber pulling groove 11, i.e. the combination between the fixed part 1 and the soft rubber part 2 can be more reliable.

In other embodiments, the flexible glue portion 2 may be fixed to the fixing portion 1 by bonding, so that the structures such as the stop portion 23, the connecting section 22, the glue pulling hole 12, and the glue pulling groove 11 may not be provided, and the structures of the fixing portion 1 and the flexible glue portion 2 may be simplified, which is beneficial to facilitating the processing of the two.

Further, the thickness direction of the hard rubber portion and the soft rubber portion 2 extends in a direction perpendicular to the first direction, and the thickness of the hard rubber portion and/or the soft rubber portion 2 is greater than or equal to 0.3mm; and/or the length direction of the hard rubber part and the soft rubber part 2 extends along the first direction, and the length of the hard rubber part and/or the soft rubber part 2 is in the range of 2.95mm-3.05 mm.

The thickness of the hard rubber part is set to be larger than or equal to 0.3mm, so that the hard rubber part can be thicker to a certain extent, namely, the fixing part 1 can be thicker to a certain extent, and the handwriting pen limiting support 10 can be stably and reliably arranged in the pen groove 20 through the fixing part 1. Setting the thickness of the soft rubber portion 2 to be greater than or equal to 0.3mm enables the soft rubber portion 2 to have a thicker thickness to a certain extent, thereby being beneficial to reliably supporting and limiting the stylus 30 through the soft rubber portion 2.

Setting the length of the hard glue portion in the range of 2.95mm-3.05mm enables the fixing portion 1 to have a relatively long length in the first direction, so that the setting range of the fixing portion 1 in the pen slot 20 can be increased in the first direction, and further the fixing portion 1 is beneficial to enabling the handwriting pen limiting bracket 10 to be stably and reliably arranged in the pen slot 20. The length of the soft rubber part 2 is set in the range of 2.95mm-3.05mm, so that the soft rubber part 2 can have a relatively long length in the first direction, the limit and support range of the soft rubber part 2 on the handwriting pen 30 can be increased in the first direction, and further the handwriting pen 30 can be supported and limited reliably through the soft rubber part 2.

The present application provides only one embodiment as to the thickness and length of the hard and soft rubber portions 2, and the remaining other embodiments of the present application will not be described in detail. Specifically, in the present embodiment, the thickness of the hard rubber portion and the soft rubber portion 2 is equal to 0.3mm, and the length of the hard rubber portion and the soft rubber portion 2 is equal to 3mm. So set up, not only can make hard rubber part and soft rubber part 2 have relatively thicker thickness and relatively longer length, but also can avoid hard rubber part and soft rubber part 2 too thick, overlength, be favorable to reducing the material quantity of hard rubber part and soft rubber part 2, and then be favorable to reduce cost.

In other embodiments, the thickness of the hard and/or soft gel portions 2 may also be less than 0.3mm, and the lengths of the hard and soft gel portions 2 may also be less than 2.95mm or greater than 3.05mm. The setting is so that the setting of the length and the thickness of the hard rubber part and the soft rubber part 2 is flexible, and the setting of the length and the thickness of the hard rubber part and the soft rubber part is convenient.

Example two

The present application also provides a mobile terminal 100, as shown in fig. 7, 8 and 9, the mobile terminal 100 includes a body 40, a stylus 30 and a stylus limit bracket 10. The pen body 40 is provided with a pen slot 20, the stylus 30 is inserted into the pen slot 20, and the stylus 30 is provided with a limit slot 301. The handwriting limiting support 10 has the same structure as any handwriting limiting support 10 in the above embodiments, and can bring the same or similar beneficial effects, and the description in the above embodiments can be referred to specifically, and this embodiment is not repeated here.

In the application, since the two functions of limiting and supporting both the handwriting pen buckle and the plastic supporting convex hull can be realized by only arranging one handwriting pen limiting bracket 10 in the pen slot 20, when the handwriting pen limiting bracket 10 is arranged in the pen slot 20 through the groove on the wall of the pen slot 20, the die of the die casting pen slot only needs to be provided with a groove die casting structure for die casting the groove, and the injection structure in the related art is not needed to be arranged, so that the structure of the die can be simplified to a certain extent, the control of the dimensional accuracy of the die is facilitated, and the improvement of the process yield is facilitated. When the handwriting pen limiting support 10 is integrally formed in the pen slot 20 through the die casting of the die casting pen slot 20, the die is only required to be provided with a corresponding injection molding structure, and a slot casting structure in the related art is not required to be arranged, so that the structure of the die can be simplified to a certain extent, the control of the dimensional accuracy of the die is also facilitated, and the improvement of the process yield is also facilitated.

According to the application, the handwriting pen limiting bracket 10 capable of realizing the limiting and supporting functions is arranged, so that the structure of the die can be simplified to a certain extent, the control of the dimensional accuracy of the die is facilitated, and the improvement of the process yield is facilitated.

In the present embodiment, the pen slot 20 is made of a relatively soft aluminum alloy, and in the first direction, the pen slot 20 is about 5mm longer than the stylus 30, and the bottom radius of the pen slot 20 is 0.15mm larger than the radius of the stylus 30. Therefore, the pen groove 20 can be prevented from scratching the stylus 30, and poor appearance of the stylus 30 can be prevented.

In the present embodiment, the pen body of the stylus 30 is made of steel, so that the pen body of the stylus 30 can be prevented from being scratched. The diameter of the circumferential surface of the groove bottom wall of the limit groove 301 is smaller than the diameter of the pen body of the handwriting pen 30 by 1mm, so that the limit effect of the handwriting pen limit bracket 10 on the handwriting pen 30 can be ensured through the limit groove 301, and the influence on the overall strength of the handwriting pen 30 due to the fact that the diameter of the limit groove 301 is too small can be avoided.

Further, as shown in fig. 9, the stopper surface 211 includes a first stopper surface section 2111 connected to a side of the flexible glue portion 2 facing the reverse direction (X2 direction in fig. 8), and the first stopper surface section 2111 is configured to be inclined gradually closer to the central axis of the stylus pen 30 in the forward direction of the first direction.

As shown in fig. 9, the groove wall of the limit groove 301 includes a first groove wall section 3011 disposed opposite to the first limit surface section 2111, and the first limit surface section 2111 is configured to have a first interval between the first groove wall section 3011 and the first limit surface section 2111 when the stylus 30 is inserted in place, the first interval being in a range of 0.295mm to 0.305 mm.

So set up for have relatively great interval between first spacing face section 2111 and the first cell wall section 3011, like this after stylus 30 inserts pen slot 20, can provide the activity space that supplies stylus 30 to move forward along the first direction, so that not only can prevent stylus 30 from outwards protruding pen slot 20 along the reverse of first direction, but also can supply the forward inwards pressing of stylus 30 along the first direction to take out stylus 30 from pen slot 20.

Specifically, in the present embodiment, the first interval is equal to 0.3mm, so that the effect of supporting and limiting the stylus 30 by the stylus limit bracket 10 can be prevented from being affected by the excessive first interval. As shown in fig. 9, the limiting surface 211 further includes a second limiting surface section 2112 and a third limiting surface section 2113 that are sequentially connected in the forward direction of the first direction. The second limiting surface segment 2112 is connected to the first limiting surface segment 2111, the second limiting surface segment 2112 is parallel to the first direction, and the third limiting surface segment 2113 is gradually inclined away from the central axis of the stylus 30 along the forward direction of the first direction.

As shown in fig. 9, the slot wall of the limit slot 301 further includes a second slot wall section 3012 and a third slot wall section 3013 which are respectively opposite to the second limit surface section 2112 and the third limit surface section 2113 in sequence, and a second interval is provided between the second limit surface section 2112 and the second slot wall section 3012, the second interval is equal to 0.05mm, and a third interval is provided between the third limit surface section 2113 and the third slot wall section 3013, and the third interval is equal to 0.05mm. It can be seen that the second limiting surface segment 2112 and the third limiting surface segment 2113 have smaller fit gaps with the corresponding groove wall segments of the limiting groove 301, and the supporting and limiting effects of the pen limiting bracket 10 on the pen 30 can be further enhanced through the smaller fit gaps.

For the first spacing, in other embodiments, the first spacing may also be equal to 0.295mm, 0.305mm, 0.4mm, or 0.2mm. Therefore, the size setting of the first interval is flexible, and the size setting of the first interval is convenient.

The handwriting limiting bracket 10 and the pen slot 20 are independent structural members which are manufactured separately.
