Description

Retractable stylus

This new creation is about a stylus, and especially a retractable stylus.

Many current portable electronic devices, such as tablet computers, smart phones, and notebook computers, all use a touch display screen to provide users with direct input of commands on the display screen to control electronic products.

Most current touch display screens use the user's finger or stylus to perform touch functions. However, in order to facilitate user operation, portable electronic devices often have a groove for accommodating the stylus. However, the existing groove design considers the user's pick-and-place action, and more The shell is formed with a broken surface or a depression to allow the user to easily apply force to remove the stylus from the portable electronic device.

Due to the limitation of the body, the groove for accommodating the stylus usually has a shorter stylus length, but for the user, the stylus with a shorter length may be difficult to grasp and not ergonomic Learning, but the length of the stylus that is easy to grasp is facing the inability to fit into a portable electronic device whose size has been limited.

Therefore, how to provide a stylus that can be smoothly accommodated in a portable electronic device and conform to ergonomics to avoid the above-mentioned dilemma is really a problem that relevant technical personnel need to think about and solve.

The novel creation provides a retractable stylus that exposes the pen tip when extended to facilitate user operation, and stores the pen tip when shortened to facilitate accommodation into a portable electronic device.

The retractable stylus created by the novel includes a first pen cover, a second pen cover, a third pen cover, an elastic piece and a pen core. The second pen cover and the third pen cover are respectively movably disposed in the first pen cover and abut against each other. The elastic member abuts between the first pen cover and the second pen cover. The refill is fixed on the first pen cover and is located in the second pen cover and the third pen cover. The third pen cover is adapted to be forced to move relative to the first pen cover to change the state of the retractable stylus. In a state, the third pen cover drives the second pen cover to move and deform the elastic member, and the second pen cover covers the pen tip of the pen core. In another state, the third pen cover is moved away from the second pen cover, and the elastic force of the elastic member drives the second pen cover to move relative to the first pen cover and abuts against the third pen cover, and the second pen cover exposes the tip of the pen core.

Based on the above, the retractable stylus fixes the pen lead to the first set, and allows the second set to move relative to the first set by the elastic member, and partially extends into the first set by the third set It can drive the second pen cover to extend or retract the first pen cover to achieve the effect of covering or exposing the pen tip, while moving the second pen cover to move away from the first pen. The telescopic effect produced by the sleeve makes the retractable stylus in the extended state convenient for the user to hold and has better ergonomic characteristics such as easy manipulation. On the other hand, the retractable stylus in a shortened state can have a smaller volume without affecting the portable electronic device to which it is applied, thereby ensuring that the portable electronic device has a light, thin and short appearance.

In this embodiment, the retractable stylus 100 includes a first pen cover 110, a second pen cover 120, a third pen cover 130, an elastic member 150 and a refill 140. The second pen cover 120 and the third pen cover 130 are respectively movably disposed in the first pen cover 110, the elastic member 150 abuts between the first pen cover 110 and the second pen cover 120, and the pen core 140 is fixed on the first The pen cover 110 partially extends into the first pen cover 110, and the second pen cover 120 and the third pen cover 130 are sleeved on the outside.

In detail, the first pen cover 110 includes a component 111 and a component 112, wherein the component 112 is a stage structure ST1 composed of a first segment 112a and a second segment 112b, and the outer diameter of the first segment 112a is greater than the second The outer diameter of the segment 112b, and the component 112 is sleeved on the inner wall surface of the component 111 with the second segment 112b. The second pen cover 120 is another stage structure ST2 composed of the third section 122, the fourth section 121 and the fifth section 123, wherein the outer diameter of the third section 122 is larger than the outer diameter of the fourth section 121 The outer diameter of the fifth section 123 is larger than the outer diameter of the fourth section 121. The third pen cover 130 includes a component 131 and a component 132, wherein the component 132 has a base 132c and a cantilever 132a extending from the base 132c, the base 132c is fixed to the inner wall of the component 131, and the cantilever 132a extends into the component 111 of the first newspaper cover 110 within. Furthermore, the refill 140 has a sixth section 141, a seventh section 142, and a fixing ring 143, and the pen tip 144 is located at an end of the seventh section 142 away from the fixing ring 143. In the shortened state shown in FIG. 1, the fixing ring 143 substantially abuts between the component 111 of the first pen cover 110 and the component 131 of the third pen cover 130, and the cantilever 132 a of the third pen cover 130 will pass through the fixing ring The opening 143a of 143 extends into and abuts against the inner wall surface of the member 111. At the same time, the portion of the third pen cover 130 that protrudes into the first pen cover 110 will also abut with the second pen cover 120 in the first pen cover 110 to have a driving relationship, which will be further described later.

FIG. 3B and FIG. 3C are schematic diagrams of some components of FIG. 3A for illustrating the assembly relationship of the components 112 of the first pen cover 110, the second pen cover 120, and the elastic member 150 in FIG. 3A, and showing different states. Please refer to FIGS. 3A and 3B first. In this embodiment, the inner diameter of the first section 112a is greater than the outer diameter of the third section 122, so the third section 122 and the fourth section 121 can be movably penetrated The first section 112a, and the fourth section 121 can also movably penetrate the second section 112b. The elastic member 150 is sleeved on the fourth section 121, and the elastic member 150 abuts between the second section 112b and the fifth section 123. As the second pen cover 120 moves relative to the component 112 of the first pen cover 110, the elastic member 150 is deformed (compressed in this embodiment) or released due to the force.

4A is a cross-sectional view of the retractable stylus of FIG. 1, and FIG. 4B is a cross-sectional view of the retractable stylus of FIG. 2, and it should be explained first that FIGS. 1, 3C, and 4A of this embodiment are the same It belongs to the shortened state, while FIGS. 2, 3B, and 4B belong to the extended state. Please refer to FIGS. 1, 3C and 4A first. In the shortened state of this embodiment, the cantilever 132 a of the third pen cover 130 extends into the component 111 of the first pen cover 110 after passing through the opening 143 a of the pen core 140. Here, the first pen cover 110 has a first groove 111a and a second groove 111b on the inner wall surface of the component 111, and the third pen cover 130 further has a convex portion 132b on the cantilever 132a. In the shortened state, the convex portion 132b will temporarily snap into the first groove 111a. At the same time, the third pen cover 130 also moves toward the second section 112b by abutting the end of the cantilever 132a against the fifth section 123 of the second pen cover 120, and then applies force to the elastic member 150 to deform it. The third section 122 of the driven second pen cover 120 thus extends out of the first section 112 a of the first pen cover 110 and covers the pen tip 144 of the pen core 140. The retractable stylus 100 of this embodiment has a length of 8.5 cm in a shortened state, so that the retractable stylus 100 has a smaller volume when not in use.

The temporary buckle mentioned here means that when the third pen cover 130 does not have any applied force, the convex portion 132b can be firmly locked in the first groove 111a without detaching, that is, once it needs to be moved In the third pen cover 130, the user must apply force to the third pen cover 130 to release the aforementioned buckling relationship.

Please refer to FIG. 2, FIG. 3B and FIG. 4B again, in the extended state, that is, when the user applies force to the third pen cover 130 and pulls its component 131 away from the fixing ring 143 of the first pen cover 110 and the refill 140 After overcoming the locking relationship between the convex portion 132b and the first groove 111a, the cantilever 132a of the third pen cover 130 will gradually pull out from the component 111 of the first pen cover 110 until the convex portion 132b is temporarily locked In the second groove 111b, the user does not need to apply any force. At this time, the second pen cover 120 loses the contact relationship of the third pen cover 130, the elastic force of the elastic member 150 can drive the fifth section 123 away from the second section 112b and drive the third section 122 to retract the first pen cover 110 The first section 112a stops until the stage structure ST2 and the stage structure ST1 are in contact with each other, so that the third section 122 of the second pen cover 120 no longer covers the pen tip 144 and exposes it, as shown in FIG. 2, The component 131 moves away from the fixing ring 143, and a part of the sixth section 141 of the refill 140 and a part of the cantilever 132a are exposed from between the part 131 and the part 111 (or the fixing ring 143). In contrast, the user can apply force to the third pen cover 130 again to restore it from the extended state of FIG. 2 to the shortened state of FIG. 1. Here, the length of the stretchable retractable stylus 100 is 11 cm, so as to facilitate the ergonomic conditions required by the user when holding it.

Based on the above, it is clear that the retractable stylus 100 of this embodiment fixes the pen core 140 in the first pen cover 110, and adopts the movable third pen cover 130 and the second pen cover 120 to allow it to There is a mutual driving relationship in the first pen cover 110, so that the second pen cover 120 can move relative to the first pen cover 110 to cover or expose the pen tip 144, and make the retractable stylus 100 reach the telescopic effect.
