Description

Technical Field

[0001] This invention relates to the field of electronic devices with an active pen, and more particularly to an elastic adjustment device and electronic device for an active pen. Background Technology

[0002] With the development of touch technology, more and more electronic devices have adopted touch for human-computer interaction. In addition to touch operation by hand, styluses have also emerged. Styluses include passive pens and active pens. Active pens emit excitation signals to create coupling capacitance between the pen tip and the screen sensor, thereby detecting the coordinates of the touch point. They also detect the tilt angle through a pressure sensor or Bluetooth device inside the pen, thereby enabling functions such as changing the thickness of the line.

[0003] Active pens can be designed with smaller tips for ease of use; they can also use pressure sensors to detect pressure at the tip, providing different line thicknesses, making them a mainstream product. However, active pens require charging. Currently, they are typically charged by attaching to the side or bottom of electronic devices, plugging into the charging port, or connecting to an external power source via a data cable.

[0004] See Figures 1-2 As shown, for charging methods where the device is attached to the sides or bottom of the electronic device 1', the charger 200' on the electronic device 1' is a single-sided elastic structure. After the active pen 300' is attached to the housing 100' of the electronic device 1', the charging contacts of the active pen 300' contact the elastic conductive piece of the charger 200'. The active pen 300' is deflected to the other side by the force of the elastic conductive piece of the charger 200', causing uneven gaps and damage to the active pen 300' within the electronic device 1'. See details. Figure 2 As shown, on the one hand, this results in an excessively large gap H between the active pen 300' and the charger 200', affecting the appearance upon shipment and potentially failing to meet shipping standards; on the other hand, it causes the side of the active pen 300' furthest from the charger 200' to rub against the housing 100' of the electronic device 1', for example, but not limited to... Figure 2 The C point in the image is damaged, thus affecting the appearance of the Active Pen 300.

[0005] Therefore, it is necessary to provide a flexible adjustment device and an electronic device that can ensure the active pen is centered in the electronic device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a flexible adjustment device that ensures the active pen is centered in an electronic device.

[0007] Another object of the present invention is to provide an electronic device that can ensure that the active pen is centered on it.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows: An elastic adjustment device is provided, installed in an electronic device and used to guide an active pen. The elastic adjustment device includes a sleeve, a movable ball, a movable ball support, an elastic element, and a base. The sleeve has receiving holes extending through both ends. The movable ball is received within the receiving holes, and one end of the movable ball protrudes from the sleeve to abut against the active pen. The movable ball support is received within the receiving holes and has a hemispherical contact surface at one end, which abuts against the movable ball. The elastic element is received within the receiving holes and abuts against the end of the movable ball support away from the movable ball. The base is installed at the end of the sleeve away from the movable ball and closes the receiving holes, and the base abuts against the elastic element.

[0009] Preferably, the end of the movable ball support with the contact surface is further provided with a limiting block, which is used to abut against the sleeve for limiting.

[0010] Preferably, the sleeve has a first end wall and a second end wall at its two ends, the receiving hole penetrates the first end wall and the second end wall, and the first end wall abuts against the limiting block.

[0011] Preferably, one end of the sleeve is provided with a first abutting part with an arc-shaped structure, and the movable ball abuts against the first abutting part and partially protrudes out of the sleeve.

[0012] Preferably, the arc surface where the first contact portion is located and the contact surface are located on the same spherical surface.

[0013] Preferably, the gap between the first contact portion and the movable ball is less than or equal to 0.1 mm.

[0014] Preferably, a second abutment is provided at one end of the receiving hole near the second end wall, the second abutment being stepped with the second end wall, and the base abutting against the second abutment and being installed on the sleeve.

[0015] Preferably, the sleeve has a support foot at the bottom and a mounting plate protruding from the side of the sleeve. The sleeve is supported on the electronic device by the support foot and connected to the electronic device by the mounting plate.

[0016] Correspondingly, the present invention also provides an electronic device, which includes a housing, a charger, and an elastic adjustment device as described above. The elastic adjustment device is mounted on the housing opposite to the charger, and the movable ball of the elastic adjustment device is offset from the elastic conductive piece of the charger. The movable ball and the elastic conductive piece are used to generate forces in opposite directions on the active pen.

[0017] Preferably, the housing is provided with a connecting post, and the side of the sleeve is provided with a mounting plate, and the sleeve is connected to the connecting post through the mounting plate.

[0018] Compared with the prior art, the elastic adjustment device of the present invention includes a sleeve and a movable ball, a movable ball support, an elastic element, and a base, which are sequentially installed in the receiving hole on the sleeve. The movable ball protrudes out of the sleeve through one end. This elastic adjustment device corresponds to the installation of the charger of the electronic device. Therefore, when the active pen is attached to the electronic device for charging, the movable ball acts on the active pen under the elastic force of the elastic element. Thus, the movable ball and the charger generate opposite forces on both sides of the active pen, thereby guiding the active pen and preventing it from deviating on the electronic device. On the one hand, it avoids the gap between the active pen and the side where the charger is located being too large, that is, it makes the distance between the active pen and the side where the charger and the movable ball are located balanced, ensuring the appearance of the shipped product and meeting the shipping standards. On the other hand, it avoids the side of the active pen away from the charger from rubbing against the shell of the electronic device during charging, thus avoiding damage to the appearance of the active pen.

It should be noted that the directional descriptions involved in the present invention, such as up, down, left, right, front, and rear, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the technical solutions of this application or / and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first," "second," etc., described are only used to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0029] First combine Figures 3-9 As shown, the elastic adjustment device 100 provided by the present invention is installed on the housing 300 of the electronic device 1 and is installed relative to the charger 200. It is used to guide the active pen 400 that is attached to the housing 300 of the electronic device 1 for charging, so as to prevent the active pen 400 from deviating or tilting.

[0030] The following is combined Figures 5-9 As shown, the elastic adjustment device 100 of the present invention includes a sleeve 110, a movable ball 120, a movable ball support 130, an elastic element 140, and a base 150. The sleeve 110 has a receiving hole 110a extending through both ends; the movable ball 120 is received within the receiving hole 110a, and one end of the movable ball 120 protrudes outside the sleeve 110. Figure 6 As shown, it is used to abut against the active pen 400; the movable ball support 130 is housed in the receiving hole 110a and has a hemispherical contact surface 131 at one end, the contact surface 131 abutting against the movable ball 120, see Figure 9 As shown; the elastic element 140 is accommodated within the accommodating hole 110a and abuts against the end of the movable ball support 130 away from the movable ball 120; the base 150 is installed on the end of the sleeve 110 away from the movable ball 120 and closes the accommodating hole 110a, the base 150 abuts against the elastic element 140, see Figure 9 As shown.

[0031] Combination Figures 6-9As shown, in one embodiment of the present invention, the sleeve 110 has a first end wall 111 and a second end wall 112 at its two ends, and the receiving hole 110a penetrates the first end wall 111 and the second end wall 112. Furthermore, the first end wall 111 has a first abutting portion 111a with an arc-shaped structure, and the arc surface of the first abutting portion 111a and the abutting surface 131 are located on the same spherical surface. Figure 9 As shown, the movable ball 120 abuts against the first contact portion 111a and the contact surface 131, and partially protrudes from the sleeve 110. Additionally, a second contact portion 112a is provided at one end of the receiving hole 110a near the second end wall 112. The second contact portion 112a and the second end wall 112 are stepped, and the shape and size of the second contact portion 112a correspond to the base 150. The base 150 abuts against the second contact portion 112a and is mounted on the sleeve 110, thereby closing the receiving hole 110a. The base 150 is flush with the second end wall 112. Figure 9 As shown.

[0032] Continue reading Figure 9 As shown, in one embodiment of the present invention, the gap L between the first contact portion 111a and the movable ball 120 is preferably less than or equal to 0.1 mm, and more preferably equal to 0.1 mm. The small gap between the two causes the movable ball 120 to have a small amount of wobbling or displacement, ensuring its stability in contact with the active pen 400.

[0033] Combination Figure 4 , Figure 6-8 As shown, the bottom of the sleeve 110 is provided with a downwardly extending support foot 114, and the side of the sleeve 110 is provided with a horizontal mounting plate 113. The mounting plate 113 is provided with a mounting hole 113a and a guide hole 113b. The sleeve 110 is supported on the housing 300 of the electronic device 1 by the support foot 114, and is guided during installation by the guide hole 113b on the mounting plate 113. The sleeve 110 is connected to the housing 300 of the electronic device 1 by the mounting hole 113a on the mounting plate 113 to realize the installation of the elastic adjustment device 100.

[0034] Continue to combine Figures 5-9 As shown, in one embodiment of the present invention, the movable ball support 130 has two limiting blocks 132 protruding from one end with the contact surface 131. The two limiting blocks 132 are symmetrically disposed at the bottom of the movable ball support 130, specifically symmetrically disposed along the axial direction of the sleeve 110. Figure 9As shown, two limiting blocks 132 abut against the first end wall 111 of the sleeve 110, thereby ensuring that the movable ball 120 cannot move when pushed by the elastic element 140, thus limiting the movable ball 120. Of course, the limiting blocks 132 are not limited to two; multiple limiting blocks 132 can be evenly arranged around the contact surface 131 to achieve the purpose of limiting and balancing forces.

[0035] In this invention, the elastic element 140 is preferably a spring, and the selection of the elastic element 140 is preferably such that the magnitude of its elastic force is comparable to the magnitude of the elastic force generated by the elastic conductive piece 210 of the charger 200 (described later). Thus, when the elastic adjustment device 100 acts on the active pen 400, the elastic force generated by the elastic element 140 can cancel out the elastic force generated by the elastic conductive piece 210 of the charger 200, thereby achieving the effect of centering the active pen 400. Of course, the elastic element 140 is not limited to a spring; other elastic components can also be used.

[0036] Combined again Figures 3-9 As shown, the electronic device 1 provided by the present invention includes a housing 300, a charger 200, and an elastic adjustment device 100 as described above. The elastic adjustment device 100 and the charger 200 are mounted opposite each other at one end of the housing 300, and the movable ball 120 of the elastic adjustment device 100 is offset from the elastic conductive piece 210 of the charger 200. (See attached diagram) Figure 4 As shown, a connector slot is formed between the two for the active pen 400 to be inserted for charging. See also Figure 3 As shown, when the active pen 400 is inserted into the insertion slot, the movable ball 120 and the elastic conductive piece 210 exert opposite forces on the active pen 400, thereby ensuring that the active pen 400 does not deviate or tilt, and making the gap between the active pen 400 and the housing 300 on the side where the movable ball 120 and the elastic conductive piece 210 are located uniform, so as not to cause friction damage to the active pen 400.

[0037] See Figure 5 As shown, in this invention, the housing 300 is provided with a connecting post 310 and a guide post 320. When the elastic adjustment device 100 is installed, the support foot 114 of its sleeve 110 is supported on the housing 300, and the guide hole 113b of the mounting plate 113 passes through the guide post 320, so that the mounting plate 113 is located above the connecting post 310, and the mounting hole 113a is directly opposite the connecting post 310. Then, the mounting plate 113 is connected to the connecting post 310 using fasteners 160 to realize the installation of the sleeve 110. The structure of other parts of the housing 300 is a conventional structure in the art and will not be described in detail.

[0038] Combined again Figures 3-9As shown, the principle and method of guiding the active pen 400 by the electronic device 1 of the present invention will be explained.

[0039] like Figure 3 As shown, when charging the active pen 400, the active pen 400 is inserted into the housing 300 from the side of the electronic device 1, that is, the active pen 400 is inserted into the insertion slot formed between the elastic adjustment device 100 and the charger 200. During the insertion process, the active pen 400 pushes the movable ball 120 to compress the elastic member 140, thus not affecting the insertion of the active pen 400, and because the surface of the movable ball 120 is smooth, it will not scratch the active pen 400. When the charging contact 410 on the active pen 400 abuts against the elastic conductive piece 210 of the charger 200, the side of the active pen 400 away from the charging contact 410 abuts against the movable ball 120 of the elastic adjustment device 100, combined with Figure 3-4 As shown.

[0040] Under the elastic force of the elastic element 140 of the elastic adjustment device 100, the movable ball 120 and the elastic conductive piece 210 exert opposite forces on the active pen 400, and the magnitudes of the forces generated by the two cancel each other out, achieving the effect of aligning and centering the active pen 400. That is, the active pen 400 does not shift or tilt. During the charging process, the position where the movable ball 120 and the active pen 400 abut is an arc surface, so the active pen 400 will not be damaged. At the same time, the active pen 400 will not rub against the housing 300 and damage its appearance. During the shipment of the electronic device 1, the active pen 400 and the electronic device 1 maintain a good shipping appearance to meet the shipping standards.

[0041] In summary, since the elastic adjustment device 100 of the present invention includes a sleeve 110 and a movable ball 120, a movable ball support 130, an elastic element 140, and a base 150 sequentially installed in the receiving hole 110a of the sleeve 110, and the movable ball 120 protrudes from the sleeve 110 at one end, and the elastic adjustment device 100 is installed corresponding to the charger 200 of the electronic device 1, when the active pen 400 is attached to the electronic device 1 for charging, the movable ball 120 acts on the active pen 400 under the elastic force of the elastic element 140. Therefore, the movable ball 120... The charger 200 and the active pen 400 exert opposite forces on both sides of the active pen 400, thereby guiding the active pen 400 to prevent it from shifting or tilting on the electronic device 1. This avoids excessive gap between the active pen 400 and the side where the charger 200 is located, ensuring a balanced distance between the active pen 400 and the sides where the charger 200 and the movable ball 120 are located, guaranteeing the appearance of the product and meeting shipping standards. On the other hand, it prevents the side of the active pen 400 furthest from the charger 200 from rubbing against the casing 300 of the electronic device 1 during charging, thus avoiding damage to the appearance of the active pen 400.

[0042] The structures of other parts of the electronic device 1 involved in this invention are all conventional structures well known to those skilled in the art, and will not be described in detail here.

[0043] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
